You can put this solution on YOUR website! A car dealership has 6 red, 11 silver, and 5 black cars on the lot. Ten cars are randomly chosen to be displayed in front of the dealership. Complete parts (a) through (c) below.
(a) Find the probability that 4 cars are red and the rest are silver.
P(4 red AND 6 silver) = (6C4*11C6)/22C10 = 0.0107
--------
(b) Find the probability that 5 cars are red and 5are black.
P(5 red AND 5 black) = (6C5*5C5)/22C10 = 0.00000928..
----------------------------
(c) Find the probability that exactly 6 cars are red.
P(6 red AND 4 other) = (6C6*16C4)/22C10 = 0.0029
