Question 1047106
 Statistics show that only 40% of South African women are overweight. Consider a randomly selected group of twenty South African women. Calculate the probability that three are overweight and none are overweight.
----------------------
P(3 are overweight) = 20C3*0.04^3*0.06^17 = binompdf(20,0.4,3) = 0.123
