You can put this solution on YOUR website! In a recent survey, 66% of the community favored building a police substation in their neighborhood. If 14 citizens are chosen, find the probability that exactly 11 of them favor the building of the police substation.
-----------------
It's a binomial proble with n = 14, p = 0.66, x = 11
----------
P(x=11) = 14C11(0.66)^11(0.34)^3 = 0.1481
