Three out of four American adults under age 35 have eaten pizza for breakfast. If a random sample of 20 adults under age 35 is selected, find the probability that exactly 16 have eaten pizza for breakfast.
p= 3/4
q= 1/4
n= 20
x= 16
----------------------
P(x=16) = binompdf(20,3/4,16) = 0.1897 =====================================================
