Question 470899: Nine percent of men and 0.25% of women cannot distinguish between the colors red and green. If six men are randomly selected, find the probability that exactly two of them cannot tell red from green. Answer by ewatrrr(24785) (Show Source):
Hi,
Note: The probability of x successes in n trials is:
P = nCx* where p and q are the probabilities of success and failure respectively.
In this case p = .09 q = .91 n = 6
nCx =
P(exactly 2 out of 6 men...) = 6C2(.09)^2(.81)^4 = 15(.09)^2(.91)^4 = .0833
