Question 1125331: Nine percent of men and 0.25% of women cannot distinguish between the colors red and green. This is the type of color blindness that causes problems with traffic signals.
(a) If 9 men are randomly selected for a study of traffic signal perceptions, find the probability that between 1 and 3 inclusive of them have this type of color blindness. Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! for 1 it is 9C1*0.09^1*0.91^8=0.3809
for 2 it is 9C2*0.09^2*0.91^7=0.1507
for 3 it is 9C3*0.09^3*0.91^6=0.0348
That sum is 0.5664
