Sixty percent of children say that chocolate chip is their favorite cookie. Fifteen children are selected at random and are asked each to name his or her favorite cookie. Find the binomial probability that the number who say chocolate chip is their favorite cookie is at least 13 children.
--------------------------
Binomial with n=15 and p=0.60
--------------------------------
P(13<= x <= 15) = 1 - binomcdf(15,0.6,12) = 0.0271
