A club with 25 members is voting on a proposal. A group of 4 has decided to vote in favor of the proposal while each of the rest of the members vote independently with a chance of 45% in favor of the proposal. What are the chances that the proposal will get the majority vote.
-----
Needed for majority vote:: >=13
Binomial Problem with n = 25-4 = 21
P(yes vote) = 0.45
-----
P(x >= 13) = 1 - binomcdf(21,0.45,12) = 0.0908
