this is a binomial problem n = 500 , p = .4 , we want probability more than 50% of 500 chose party X. so more than 250 So we want the cumulative probability of x = 251 , 252, 253, ... 499 , 500 Do you have a solution in your book?

this is a binomial problem n = 60, p = .4 , we want probability more than 50% of a sample of 60 chose party X. So we want probability of more than 30 So we want the cumulative probability of x = 31 , 32, 33, ...58,59,60

on a TI 83 calculator you can solve 1  binomcdf( 60, .4, 30) , that will give you probability there is more than 50% choosing party x in your sample
