You can put this solution on YOUR website! According to a recent report, 0.27 is the probability that an American adult female has high cholesterol requiring treatment. Five American adult females are randomly selected. What is the probability that exactly 2 of the 5 have high cholesterol requiring treatment?
---------------------
Binomial Problem with n = 5; p(h chol) = 0.27 ; p(not h chol) = 0.73
---------------------
P(x=2) = 5C2*(0.27)^2*(0.73)^3 = binompdf(5,0.27,2) = 0.3826
