Approximately 9 of men have a type of color blindness that p

Approximately 9% of men have a type of color blindness that prevents them from distinguishing between red and green. If 3 men are selected at random, find the probability that all of them will have this type of red-green color blindness.

Solution

X no of colour blindedness people follows a Binomial distribution with p =0.09

n =3

Required prob = the probability that all of them will have this type of red-green color blindness.

= P(X=3) =

0.000729
