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 binomial with n= 14 ; p = 2/3 ; and x = 11
---
P(x=11) = 14C11(2/3)^11*(1/3)^3 = binompdf(14,(2/3),11) = 0.156
