The percentage of Americans who are vegetarians is 3.2%. Four people are randomly selected and are asked if they are vegetarians. Find the probability that exactly one person said he or she is a vegetarian.

Binomial Problem with n = 4 and p(vege) = 0.032
---------------------------
P(x = 1) = 4C1(0.032)(0.968)^3 = binompdf(4,0.032,1) = 0.1161
