Probability help?

a carton contains 4 black bricks, 5 white bricks, and 3 brown bricks. If bricks are drawn at random without replacement, what is the maximum number of bricks that could be drawn without picking a black brick?


a) 4 b) 5 c) 6 d) 7 e) 8





pls show work or give me a formula

Probability help?
e) 8





It is theoretically possible to draw a combination of 5 white bricks and 3 brown bricks (5+3=8), leaving the 4 black bricks. Not likely, but it could happen.
Reply:8
