I'm lost on how to work with probability..please help?

1. The following data represents the number of games played in each World Series from 1923 to 2005.


x (games played) Frequency


4------------------------------------- 15


5------------------------------------- 15


6------------------------------------- 18


7------------------------------------- 33





a) Construct a discrete probability distribution for the random variable X.


b) Sketch the probability histogram.


c) Compute and interpret the mean of the random variable X.

I'm lost on how to work with probability..please help?
Yes! You definitely need help!!!!





You must define Random Variable "x". Is it "Year"?? Is it "World Series game number 4"? or something else???





"Frequency" is meaningless unless Random Variable "x" is defined.


Statistics. Please Check.?

(F14)


Identify each of the random variables as continuous or discrete.





a) Speed of an automobile


Continuous





b) The number of doughnuts left in the pantry


Discrete





c) The air temperature of a public park


Continuous





d) The weight of a professional wrestler


Continuous





e) The number of restaurant patrons


Discrete





F(1)


For the information (a) to (e) list the highest level of measurement as ratio, interval, ordinal, or nominal.





A book inventory record contains the following information:





a) Title: More Mysteries


Ordinal





b) Author: Roger Mortimer


Nominal





c) Date of publication: 1998


Interval





d) List price: $25.00


Ratio





e) Number in stock: 6


Ordinal

Statistics. Please Check.?
F14)





think of continuous random variables as anything that can take on any value on a defined interval of the real number line.





think of discrete values as anything that has values that are only points on the number line.





a) continuous


b) discrete


c) continuous


d) continuous


e) discrete








F1)





ordinal - values are only important for a measure of sequence, 1st place, 2nd place...





on a scale of 1 to 10 rate your joy with ....





a Likert Scale, i.e., strongly disagree, disagree, neutral, agree, strongly agree





Nominal - also called categorical, order does not matter. things such, e.g., color, gender.





interval - anything that measure the difference between to measurements. for example the difference between 100 feet and 90 feet is the same as the difference between 70 and 60 feet. Temperature is a good example





ratio - same as interval but with a defined value of 0.





a) I'd say the title is a categorical variable, it's ordinal if used to order the books by title





b) categorical





c) interval





d) ratio





e) ordinal

Help? math questions... i suck @ math...heheh?
1.


62 1/2 * 76 4/5 cm


= 62.5 * 76.8 cm


= 62.5 * 0.768 m


= 48


Correct answer us C





2.


Area of the smaller circle = (pi) r^2


Area of the bigger circle = (pi) (2r)^2 = 4 (pi) r^2





Probability that a point in the bigger circle is inside the smaller circle: (pi) r^2 / 4 (pi) r^2 = 1/4





Probability that a point in the bigger circle is outside the smaller circle: 1 - 1/4 = 3/4





Correct answer is E





3. I have to think about this one





4.


10111101(two) = 189(ten) = 21000(three)


Correct answer is D





5.


-19/30 = -0.63333


-17/26 = -0.65384


-13/20 = -0.65


-15/23 = -0.65217


-14/27 = -0.51851





In ascending order


-17/26, -15/23, -13/20, -19/30, -14/27





Correct answer is A





6.


Surface area of a sphere = 4 (pi) r^2


= 4 (pi) (2sqrt(3))^2


= 4 (pi) (4*3)


= 4 (pi) 12


= 48 (pi)





Correct answer is E





I hope this helped

Find the expected value of X?

A fair die is rolled and the number of dots showing is recorded. A random variable X is defined to be 1 if the result is greater than 3, and 4 if the result is less or equal to 3.





a. 1/2


b. 5/2


c. 9/2


d. 11/2


e. none of the others

Find the expected value of X?
x1*p(x1) + x2*p(x2)





x1 = 1 for event dots%26gt; 3,


x2 = 4 for event dots%26lt;=3.


These are equally probable because there are 6 dots on the die.





1*(1/2) + 4*(1/2)
Reply:i dont get it......but still 10x 4 d points
Reply:do your own homework!!





Sheesh





think about it.


how many sides on a fair die (this is not Dungeons and Dragons so we can safely assume 6)





so with a 6-sided die and if the number rolled are one of the numbers 4,5,6 (which co-incidentally is half of 6) it gets a value of 1 and if its numbers 1,2,3 it gets a value of 4.





so its a 50:50 chance that a value of 1 or 4 is produced (kinda like flipping a coin) so what would happen if first a 1was rolled on the die and after that a 6 was rolled - what would x be equal to?

Sorry, this is a scam. BMW doesn't run any lotteries like this (see the links below for more details)... it's just a variant of advance fee fraud (also know as a 419 scam). First, you (and thousands of other people) get a spam message stating that you won the lottery. If you believe the scammer and reply, he will charge you a fee before your winnings can get to you: in this case, it's probably to pay shipping fees for your "new car". The whole thing is made up just to steal your cash.
Reply:BMW uses their own domain - not hotmail. It's a fake e-mail. Mark it as spam, delete it, and don't let it bother you again.

P101 questions, help me please?

20. A proponent of ESP claims that ESP shows up only when the vibrations are right and that there is no way to know whether the vibrations are right except to see whether ESP shows up. What is wrong with this theory from a scientific standpoint?


a. It relies too heavily on operational definitions.


b. It relies too heavily on negative correlations.


c. It is not falsifiable.


d. It has too many dependent variables.





26. To test the effect of soothing music on intellectual performance, Professor Bach plays soft background music during her morning class and no music during her afternoon class. She then counts the number of "intelligent questions" and reports more in the morning class (with music). What two things does this experiment lack that it should have had in order to justify the conclusion?


a. random assignment and blind observations


b. demand characteristics and an independent variable


c. blind observations and a dependent variable


d. random assignment and an independent variable

P101 questions, help me please?
20


it is circular.


i could argue for any of them EXCEPT D





26





c ( and i would want random assignment also)


the real problem here is that the "experiment" is confounded by time of day, which might be the causative factor.


Math question?

A company produses pushpins in the percents shown in the table.The school secretary opens a large bag of pushpins.She putsthe pins into small boxes to distribute to teachers.She puts 50 pins in each box.





color percent


white 15%


yellow 10%


red 15%


orange 20%


green 15%


blue 25%





A. how many pushpins of each color do u expect to be in each box?





B. how do u expect the number of pushpins of each color to vary across the samples?





C. u can simulate filling the boxes by generating random integers from 1 to 20.Which numbers would u let represent each color?How many random numbers do u need to generate to simulate filling one box?





D. Carry out the similation describe in part (c) 3 times.Compare the distributions of colors in your similated samples with the expected distribution from part (A).





E. s\Suppose the Secretary selects a random sample of 1,000 pushpins from the bag.How closely would u expect the percent in the table?

Math question?
Change % = numbers


A. white .15 *50 =7.5


yellow .10*50 =5


red .15*50= 7.5


orange .20*50=10


green .15*50=7.5


blue .25 *50=12.5





I don't think you measure pins in half but...
Reply:A, multiply each percent by 1/2 (IE orange = 20% *0.5 = 10 pins)





B, depends on how the manufacturer labels them and how "large" the secretary's large bag is .. shoudl be very little variation.





C,


1-5 = Blue


6-8 = green


9-12 = orange


13 - 15 = red


16 %26amp; 17 = yellow


18-20 = white


... you need to generate 50 random numbers





D, ... YOU need to do this, this is your math homework and you have an "approved" method of generating random numbers from your teacher.





E, same as answer B


This is a stats question, divided to 3 parts... So bear with me?

a) Fish are bred in large batches and allowed to grow until they are caught at random for sale. When caught, the length of the fish are normally distributed with Standard Deviation 2 cm and only 10% of the fish %26lt; 7cm long. Find the mean length of the caught fish.





b) A large number, n of fish are caught at random for sale and it is required that the probability of there being 10 or fewer fish in the catch which measure %26lt; 7 cm long is to be 0.025 or less. using a suitable approximation, derive the approximate inequality





n^2 - 245n + 11000 ≥ 0





c) Find the least possible of fish to be caught





I'm frustrated... I couldn't understand the second part of the question. But I know how to solve the first part.

This is a stats question, divided to 3 parts... So bear with me?
Hi. Do you understand standard deviation? And how it forms a bell curve. These are mathematically related, and it's the relationship you have to 'get'. The rest is plugging in numbers.
Reply:Hi,


pl. contact me for solution.





I have master degree in mathematics and I have got thirteen ten years of teaching experience in Math at college level and currently I am working as a lecturer for an army engineering college author of math guide.


thankyou


Does any one have AOL or aim phone line??

please please please if you have it do you know how to get rid of it??? b/c you have to register for it and everything and it gives you a phone number... but i dont want it anymore b/c i get like 1,000,000 calls a day from random numbers and its sooo annoying. PLEASE HOW DO I UNREGISTER FOR THIS!

Statistics/probability?

A box contains 5 white tags numbered 1 to 5, 5 red tags numbered from 1 to 5, and 5 green tags numbered from 1 to 5. If two tags are selected at random and without replacement what is the probability that:





a) both are the same number?


b) both are the same color?


c) they are consecutive numbers but of different colors?


d) they are consecutive numbers of the same color?








If you could please explain in more detail, I'd really appreciate it!

Statistics/probability?
First, the total number of combinations is actually 15 choose 2 = 15*14/2*1 = 105, since the order in which you pick them doesn't matter.


a) There are three ways to pick two 1s: red and green, red and white, or green and white, for 3 possibilities. Likewise there are 3 possibilities for 2s, 3s, 4s, and 5s, so that gives 15 ways to pick two of the same number; thus the probability is 15/105 = 1/7.


Another way to see this is this: after you pick the first tag, 2 of the 14 remaining tags match its number. Thus the probability that the second one matches is 2/14=1/7.


b) How many combinations of two red tags are there? 5 choose 2 = 10. (R1R2, R1R3, R1R4, R1R5, R2R3,...) There are also 10 combinations of two green tags and 10 of two white tags, so that gives 30/105 = 2/7.


Again, we can also see this by pulling the first tag and realizing that 4 out of the remaining 14 tags match in color, so the probability must be 4/14=2/7.


c) This one is a little harder. How many ways can you pull a 1 and a 2 of two different colors? They can be RG, RW, GR, GW, WR, or WG, so that's 6 combinations. Likewise for a 2 and a 3, 3 and a 4, or 4 and 5...each have 6 combinations. That's 24 total combinations, so the chances are 24/105=8/35.


d) This one is easier to count: we can get R1R2, R2R3, R3R4, or R4R5 in red for 4 combinations. Counting 4 more for green and 4 more for white gives 12 total combinations, for a probability of 12/105=4/35.
Reply:There are C = 15 x 14 = 210 possible combinations.





a) 5 x 2 = 10, so 10/210 or 4.76%





The first one can be any number 1-5. The second one must be the same number but of a different color (there are only two possibilities).





b) 3 x (5)(4) = 60, so 60/210 or 28.57%





The first one can be any number 1-5. The second one must be the same color (there are four left). And there are three colors.





c) 3 x (4)(2) = 24, so 24/210 or 11.43%





The first one can be only 1-4. The second one must be a specific number of a different color (there are two of these possible). There are three colors.





d) 3 x (4)(1) = 12, so 12/210 or 5.71%





The first one can be only 1-4. The second one must be the next number in the same color (there is only one possibility). There are three colors.

If your email address does not meet these requirements, you will be given an opportunity to submit an alternate email address. Some internet service providers such as Yahoo and Hotmail.com provide free e-mail services. Some companies provide free internet access and may also be available at your public library.





Each day a certain number of ads or questions will be posted at the game site that will remain on the site all or part of that day. To submit your entries for the daily contests, choose your numbers for each of the FreeLotto® games you are eligible to enter each day and choose a sponsor to visit by clicking on its banner ad, or answer a multiple choice question. You may submit one entry for each game available to you on a given day. You may also increase the number of banner ads available to you by answering questions regarding your buying preferences. Your answers will determine if some advertisers who seek to selectively advertise their products will display their ads to you. (Example: if you indicate an interest in fishing, fishing related ads may appear on your FreeLotto® game page). You may enter once from each ad or question but you are limited to one entry per FreeLotto game per day.)





2. Players have the opportunity to play the 6 consecutive FreeLotto® games consisting of FreeLotto, FreeLotto Win A Car, FreeLotto Pay Off your Mortgage, FreeLotto FastCash, FreeLotto $100,000 GiveAway and FreeLotto SuperBucks each day. (The FreeLotto® game sequence consists of 6 games which must be played in consecutive order). Players must play each game they are offered in succession to be eligible to play the subsequent game and must enter all of the first 5 games they are offered to be eligible to play FreeLotto SuperBucks. The 5 games that follow Classic FreeLotto® are FreeLotto Win A Car, FreeLotto Pay Off your Mortgage, FreeLotto FastCash, FreeLotto $100,000 GiveAway and FreeLotto SuperBucks. From time to time the FreeLotto games may be offered individually or out of sequence. In such instances all other provisions of the FreeLotto Game Rules apply.





3. How to Play FreeLotto Games:


a. Classic FreeLotto


1. To enter the daily Classic FreeLotto® sweepstakes, you will need to pick 6 different numbers between 1 and 54, with no duplicates. This can be done by one of three methods: (a) pick 6 unique numbers; (b) allow the computer to pick the numbers (referred to as a "Quick Pick"); or (c) designate and save 6 numbers as "Favorites" which can be automatically selected instead of selecting unique numbers each time you enter; or (d) click on “Hot Numbers” which allows the computer to pick your numbers based on the most common drawn winning numbers.





Each day, six (6) Classic FreeLotto winning numbers between one 1 and 54 will be selected at random via a random ball drop lottery machine at around 5:00 PM Eastern Time (New York Time). These numbers will be matched against all entries received between 3:00:01 PM Eastern Time (New York Time) the previous day and 3:00 PM Eastern Time (New York Time) that day. The winning numbers will be posted after the drawing on the FreeLotto® website.





2. Classic FreeLotto Prize: If an entry identically matches each of the 6 winning numbers that appear on FreeLotto the ball drop, that entry will be awarded the Grand Prize, pending eligibility verification and the administration of a skill-testing question (referenced below) if the entrant is from Canada. Second prizes will be awarded for matching 5 of the 6 numbers drawn, third prizes shall be awarded for matching 4 of the 6 numbers drawn, and fourth prizes shall be awarded for matching 3 of the 6 numbers drawn. The FreeLotto daily results email is the sole notification of any prize winnings and prize winners must claim any prize by following the instructions within the FreeLotto daily results email. Classic FreeLotto® GRAND PRIZE: One Million ($1,000,000.00) US Dollars, paid out as an annuity of $40,000.00 per year for 25 years. If more than one entry contains all of the winning numbers, the Grand Prize will be divided evenly among the correct entries. Cash prizes for multiple Grand Prize winning entries will be paid out as an annuity based upon dividing the Prize by the number of winning entries, which will be paid out over 25 years. SECOND PRIZE: $300.00. Maximum cumulative dollar amount awarded for any drawing for the 2nd prize in the FreeLotto game is $250,000.00. Therefore, if there are more than eight hundred thirty three (833) 2nd Prize winners in any FreeLotto drawing, then those 2nd Prize winners for that drawing will be awarded an amount equal to dividing $250,000 by the number of 2nd Prize winners. (Example: if there are 1,000 2nd prize winners, each 2nd Prize winner would receive $250.00 ($250,000/1,000 = $250.00)). ALL OTHER PROVISIONS OF THE FreeLotto® GAME RULES APPLY. THIRD PRIZE: $5.00 to each winner. FOURTH PRIZE: $1.00 to each winner. The winning numbers will be posted after the drawing on the FreeLotto® website http://www.freelotto.com.

FREELOTTO?is it TRUE or LIE?PLEASE HELP %26amp; THANKS!?
I agree with the first comment, too much to read.





Looks like a variation of the pop ups that promise a prize for completing a survey. The problem is, the odds of winning are not worth the amount of time it takes to complete the surveys.





These sites make money by referring you to web sites that pay for each visit. You have to click on an awful lot of websites for them to make enough to give away.
Reply:Nobody is going to read all that.....





Go here:

or Google "Freelotto"..





Many are scams....caveat emptor.

I need help solving a finite mathematics problem.?

This is not my homework. This is from a sample test. I got 3/35 when i figured it out so i just selected 4/35. The answer is D. can anyone tell me how to do this?





A box contains 4 red balls and 3 blue balls. Four balls are selected simultaneously at random and their


colors are noted. A random variable X is defined to be the number of red balls minus the number of


blue balls. Find Pr[X = 2].





(a) 4/35 (b) 1/7 (c) 2/5 (d) 12/35 (e) 4/7 (f) none of the others

I need help solving a finite mathematics problem.?
To have 2 more red balls than blue balls, when only 4 balls are selected, you must choose 3 red balls and one blue ball.





Let C(n,k) = n!/[k!(n-k)!] be the binomial coefficient "n-choose-k", the number of ways to choose k objects from a set of n.





There are C(7,4) = 7!/[4!3!] = 35 ways to choose 4 balls. Of these ways, how many include 3 red balls and one blue ball? There are C(4,3) = 4 ways to choose the 3 red balls, and C(3,1) = 3 ways to choose the 1 blue ball, so there are 4*3 = 12 ways to choose a combination including 3 red balls and one blue ball. Therefore, 12 of the 35 possible combinations will give X=2.
Reply:The answer is simpler than it appears.





Take four red balls named a, b, c, d and three blue ones named e, f, g.





If you select four total balls and the number of red must be exactly 2 more than the number of blue, then you must select three red balls and one blue ball. It's the only combination that totals four with a difference of two.





There are only four ways to select three red balls from four (abc, abd, acd, bcd) and only three ways to select one blue ball from three (e, f, or g).





Four ways times three ways is twelve ways!





It looks like you already figured out where the 35 came from, but for those who didn't:





1. You have 7 choices to select the first ball, 6 choices for the second, then 5, and 4. That's 840 possibilities.





2. Then you divide this number by 24 (4 x 3 x 2 x 1) which eliminates the duplicate selections. If you select balls abcd this is exactly the same as selecting bacd.





3. 840/24 = 35.
Reply:You have to multiply that by 4 because the order doesn't matter.


4(4/7 * 3/6 * 2/5 * 3/4) = 4(3/35) = 12/35


You could have drawn the blue one first or second or third or fourth.


You could have


BRRR, RBRR, RRBR, or RRRB
Reply:Let us know what you found
Reply:You have to know which balls you are talking about, the balls picked or the balls left.

Probability?

A box contains 5 white tags numbered 1 to 5, 5 red tags numbered from 1 to 5, and 5 green tags numbered from 1 to 5. If two tags are selected at random and without replacement what is the probability that:





a) both are the same number?


b) both are the same color?


c) they are consecutive numbers but of different colors?


d) they are consecutive numbers of the same color?








My initial guess for completing a %26amp; b is to take 5/15 x 4/14 + 5/15 x 4/14 + 5/15 x 4/14 = 0.2856, but I don't think this is completely correct, and I don't know what to do to differentiate between being the same color or the same number.





If you could please explain in more detail, I'd really appreciate it!

Probability?
You can simplify the first cases:


a) Here you can just imagine that you pick a certain number (let's say '1'). What's the chance that the second tag matches? There are 2 other tiles with '1' on them (out of 14), so the probability is 2/14 or 1/7. Notice how the number of the tag doesn't matter.





Same thing for b)


Imagine you pulled a green tag. The chance that the second tag is also green (4 remaining) is 4/14 or 2/7. Again notice how the color of the first tag really doesn't matter.





c) Break down the 5 cases:


Draw a '1' --%26gt; second tile must be '2' of another color (2/14 = 1/7)


Draw a '2' --%26gt; second tile must be '1' or '3' of another color (4/14 = 2/7)


Draw a '3' --%26gt; second tile must be '2' or '4' of another color (again 2/7)


Draw a '4' --%26gt; second tile must be '3' or '5' of another color (again 2/7)


Draw a '5' --%26gt; second tile must be '4' of another color (1/7)





So the odds are (1/5)*(1/7) + (1/5)*(2/7) + (1/5)*(2/7) + (1/5)*(2/7) + (1/5)*(1/7). This is simplified to (1/5)(1/7 + 2/7 + 2/7 + 2/7 + 1/7)





= 1/5 * 8/7 = 8/35





d) is similar to c) but with the same color.


If 1 or 5, then only 1 other tile (out of 14) will match.


If 2 though 4, then 2 other tiles (out of 14) will match





1/5 * (1/14 + 2/14 + 2/14 + 2/14 + 1/14)


1/5 * (8/14)


1/5 * 4/7


4/35
Reply:a) both are the same number?


well the first time you can pick anything, the second one needs to match the first number, so if there are 3 of each number; then the answer is 2/14 = 1/7





b) both are the same color?


same logic to this one, first time you can pick anything the second one needs to match the first color. There are 5 of each color, so the answer is 4/14 = 2/7





c) they are consecutive numbers but of different colors?


I'm thinking you can pick 5, 4, 3 or 2 first because if you pick 1, there is no number to pick after it. So the first fraction is 12/15 = 4/5. We want a different color, so we only have 2 options for the second pick; 2/14 = 1/7


Multiply: 4/5 x 1/7 = 4/35








d) they are consecutive numbers of the same color?


4/5 is still the first fraction. Same color means 1/14 for the second fraction. Multiply 4/5 x 1/14 = 4/70 = 2/35








I hope my thinking is right :-)

n so on
Reply:A) the answer is arrived at by figuring how the numbered tags change with each draw. At first there are 3 of each number, so the odds of getting any one number is 5/15, or 1/3. Once the that number is drawn, there are only 2 of that number left, so that would mean there are 2/14 odds of drawing the same number, which is 1/7. The total odds would be 1/3*1/7 or 1/21.


b) using the same arguement as above for colors, the odds would be the same.


c). the odds here are a bit harder to compute, since there are two cases to consider. If one considers that the next "consecutive" number to the 5 is 1 then it is pretty straightforward. If not then there are a different set of calculations to do.


Case 1: 1 is consecutive to 5: drawing any number is 1/3. therefore there are only 4 possible tags to complete the sequence, so it would be 4/14 to pick from or 2/7. the answer would be 1/3*2/7.


Case 2: 1 is not consecutive to 5. If you draw a 1 or 5 then the chances are there are only 2 tags that work, thus 2/14 or 1/7 chances. answer is 1/3* 1/7


d) 1/3 * 2/14
Reply:a). after drawing the first tag, there are 14 tags left, 2 of which are the right number. prob = 2/14 = 1/7





b) after drawing the first tag, there are 14 tags left, 4 of which are the right color. prob = 4/14 = 2/7





c) if the first tag is numbered 1 or 5, only 2 of the remaining 14 tags work


if the first tag is 2,3, or 4, 4 of the remaining tags work (2 possible numbers, 2 colors).


2/5 * 1/7 + 3/5 *2/7 = 8/35





d) if the first tag is numbered 1 or 5, only 1 of the remaining tags works.


if the first tag is numbered 2, 3, or 4, then 2 of the remaining tags work


2/5 * 1/14 + 3/5 * 2/14 = 4/35


Alcohol question anyone ???

My boyfriend is taking me to a family party. I have only drank 4 times before this and one of those times I threw up, but thats b/c I had around 5 shots of random alcohol, and until about 2 in a half hours later I threw up after drinking. Now I'm 19, 5'3'', about 115 lbs. He says theres only going to be Bacardi Superior which is .40 proof.





I don't want to throw up again and have him take care of me all night, but I still want to get a buzz and feel something and have a good time.





I was wondering how many shots would be a comfertable stage for me, so I dont get the feeling of throwing up, and I'm not drinking on an empty stomach.





And I'm most likely going to be mixing it with pepsi and we're using the standard party cups that you use for beer pong. So how much would I mix of Bacardi and pepsi to have a good taste and get me a buzz.





So if you could give me info. on the number of shots strait up, and how much to mix pepsi and bacardi in the party cups that would be great. TY

Alcohol question anyone ???
The fact that you even have to ask implies that you are drinking for the wrong reasons. Drink socially and a nice buzz will accompany you. Don't drink with the intent to get drunk or buzzed. Also your big story makes you seem a little needy to brag about drinking. Drinking to impress people certainly is not cool and is also the wrong reason to drink.
Reply:well you should get a minimum drink because your body cannot handle the liquor.


also, i think mixing with drinks is a good idea.
Reply:Eat something greasy like fries or something like that.Dont drink more than 2 drinks %26amp; it will start giving you a little buzz Stop at this point or you will throw up.
Reply:OK you going to a family thing so do you really want to risk making a *** of your self in front of his family if you drink to much think about that.


but for you question make sure your drinks are not Strong drink slow and don't take no shots
Reply:In your state is it legal for 19 yr olds to drink? If not then you should drink STRAIGHT Pepsi! If you can drink legally at 19, then one shot of rum in your Pepsi is all you need for all night.
Reply:2 -3 shots should be fine...but space them out over 30-40 minutes.





So you only need to do a 1/4 Bacardi to 3/4 Pepsi...(since you already have a good buzz from the shots).





Eat 1-2 hours before drinking. Bread, and meats are key (for absorbtion).
Reply:First of all, you're 19 so you shouldn't be drinking to begin with... But most of us do it and so did I so whatever... Your choice...





Don't feel any pressure from your boyfriend or ANYONE else to drink, or drink more... You need to take it slow and listen to your body....





Based on your height, weight, and tolerance... I'd say no more than 2-3 shots, or 2 mixed drinks... And please don't slam down your mixed drinks, sip on them...





When you drink fast your body doesn't realize how intoxicated you are getting until it's too late usually... Which is when you would throw up!





Alcohol kicks in pretty quickly, but not immediately... So take your time... Also, have a glass of water after each drink to prevent dehydration and hangovers.





Good luck and be safe!
Reply:probably one, or two at the most. I wouldnt drink beyond that. And drink beer the rest of the night after that.
Reply:that really depends on if you can handle your alcohol... what i do after im already tore up, i normally will sit down and eat something like a piece of bread, normally i eat about a half of a cup of multi grain cherrios, it works for me and my friends.... Try taking some cherrios in your purse, and when you feel like youve had enough eat some.... I havent had a hangover nor have i thrown up doing this method, i highly recommend it....
Reply:This is a question only you can answer. It all depends on how high your tolorant is.





Just remember, it take about 1 hour for 1 shot/drink of liquor to be filitered through your liver. As the night goes on and you keep drinking, it takes longer and longer for your liver to filter the liquor and this is way you become drunk.





If you can pace your self throught out the night you could have quite a few shots. Just when you start to feel buzzed, take a break and drink some water. This way you can still get buzzed but not get trashed and look like a fool.





Also make you eat a good meal befor hand. (Don't eat a salad or a few shrimp. Eat a full meal) This is going to help you absor some of the liquor. Also when you start to fell buzzes and not good, eat some bread/crackers to help.





The amount of liquor you pour in the glass, depends on how high your tolorant is and how fast you want to get drunk. The less liquor in the cup the more you can drink, then more liquor, the less you can drink. If the drink is not strong enough you can always add more liquor. But if it's to much, you can not take it out.
Reply:don't drink alcohol is bad for you anyways

Reply:1. I'll assume you meant the spinner has 5 sections since you gave 5 letters it could be. On the cube you have 3 even and 3 odd, so the chance of getting an even number is 3/6 and the chances of not rolling a C is 4/5. So you multiply the two (3/6)*(4/5)=0.40 or 40%





2. From 0-99 the prime numbers are 2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71 73 79 83 89 97. If you count them up, there are 25 of them. There are 100 faces on the cube, so you have a 25/100 chance of rolling a prime number.





3. There are 3 even and 3 odd numbers on the cube, so you have a 3/6 chance of rolling an odd number. 3/6=0.50 or 50%





4. There are 46 marbles in all. There are 21 pink and yellow marbles. 21/46=0.45652 or rounded to the nearest hundredth is 0.46

c_ exactly 6 of the cars are black


d) between 1 and 4 cars are inclusive are black


e) no more than 3 cars are black


f) more than 20 of the cars are not black?





i dont get this math question. can someone please help me and explain it

Statistics help?
Let X be the number of black cars. X has the binomial distribution with n = 25 trials and success probability p = 0.20





In general, if X has the binomial distribution with n trials and a success probability of p then


P[X = x] = n!/(x!(n-x)!) * p^x * (1-p)^(n-x)


for values of x = 0, 1, 2, ..., n


P[X = x] = 0 for any other value of x.





this is found by looking at the number of combination of x objects chosen from n objects and then a total of x success and n - x failures.





the mean of the binomial distribution is n * p


the variance of the binomial distribution is n * p * (1 - p)





a) the mean is 25 * 0.20 = 5





b) variance is 25 * .2 * .8 = 4





c) P(X = 6) = 0.1633459





d) P(1 ≤ X ≤ 4) = P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4)


= 0.02361183 + 0.07083550 + 0.13576804 + 0.18668105


= 0.4168964





e) more than 20 are not black is the same as less than five being black.





P(X %26lt; 5)


= P(X = 4) + P(X = 3) + P(X = 2) + P(X = 1) + P(X = 0)


= 0.186681050 + 0.135768036 + 0.070835497 + 0.023611832 + 0.003777893

b) variance = np(1-p) = 25(0.20)(0.80) = 4





c) P(6 black) = 25!/(6!(25-6)!) 0.20^6 0.80^(25-6) = 0.163346
