Nine percent of adult males connot distinguish between the colors green and red. if samples of 10 men is taken.
A)what is the expected number of re/green colorbind men in the sample?
u = np = 10*0.09 = 0.9
------------------------------------
B( calcute the exact probability that 3 of the men will be red/green colorblind?P(x = 3) = 10C3*(0.09)^3*(0.91)^7 = binompdf(10,0.09,3) = 0.0452
