  1. In the United States, approximately 8% of men suffer from color blindness.
AChoose two men at random. What is the probability that both are colorblind?
BChoose one man at random. What is the probability that he is not colorblind?
CChoose two men at random. What is the probability that neither are colorblind?

Verified Answer :

AThe probability that the first man is colorblind is .08, and the probability that the second is colorblind is also .08, so the probability that both are colorblind is .08.08=.0064.

b.  The probability that he IS colorblind is .08, so the probability that he is not is 1-.08=.92.

c.  Similarly to part a, we can calculate this probability as .92.92=.8464.
