Many cars have keyless entry.?

Many cars have keyless entry. To open the lock you may press a 5-digit code on a set of buttons. The code may include repeated digits like 11433, 55512. How many different 5-digit codes can be made using 1-10 if repetition is permitted? B) How many different ways are there of pressing 5 buttons if repetition is allowed? C) a burglar is going to press 5 buttons at random, with repetition allowed. Find the probability that the burglar hits the sequence to open the door. D) suppose that each button had only one number associated with It as (1, 2, 3, 4, 5) how many different 5 digit codes can be made with the 5 digits if repetition is permitted? E) using the buttons labeled 1-5, how many different ways are there to press 5 buttons if repetition allowed. Find the probability that the burglar hits the sequence to open the door. G) Is a burglar more likely , is he or she less likely, or does he or she have the same likelihood of pressing 5 buttons and opening the car door if the buttons are labeled as in the first illustration or as in the second illustration? Explain h) can you see any advantages in labeling the buttons as in the first illustration?

Many cars have keyless entry.?
It is a matter of safety...





In a car sales agency, they provide you, the legitimate owner, with a set of two keys, and a code, written both, in a detachable part of the car national ID number, and also printed in the dorsum (i.e. upper part) of the computer module pannel, that you see, only if you take off the motor covering or the covering of the computer module.....


Yes, most cars have a sequence of five combinations as you describe, in pairs...and they count as five digits....


You can either leave the original number, or progran (reset) your own sequence...(so you can remember it,,)


The number of sequences that you have to "try", in order to hit the proper one, just by sheer chance or chance, is the number (5) of combination, multiplied by all possible combination of 5 sequences...that is Gx5x5000= 25.000


It means that you can have 25,000 combinations of the sequence, and if you want to open a car without the keys, and using the sequence alone, you wil make the car beep loudly with the second failed "guessed" attempt, and you will spend in average, 9 hours with a good paper book, writing the tried (essayed) combinations, before you hit by accident, the correct one...


By then, you will have in the first minutes, surrounding you and you car (or anybodies car for that matter), the neighbors, the police, the firefighters, and other security forces, trying to help you., ( normally trying to open your door by blowing in pieces the side car window), or opening the door with a crane bar....or arresting you, if you are not the legitimate owner of the car.....


It has been deviced in that manner...(8 out of 10 cars in mexico, use the sequence 1-2 3-4 5-6 7-8 9-0, and the car computer reads each combination of two, as one digit......


I Live in Mexico City, where car theft is rife, and daily, the theft of auto-spare parts, is kind of a daily sport, I protect my car with special double transistored keys...and the 5 digit sequence....


If the sequence fails, its good to carry a dummy key in your wallet...(that will at least disconnect the alarm, and will open the door for you....


Good luck
