You can put this solution on YOUR website! Suppose that 68% of married couples paid for their honeymoon themselves. You randomly select 6 couples and ask each if they paid for their honeymoon themselves.
Find the probability that the number of couples who say they paid for their honeymoon themselves
(A) exactly 4 couples, = binompdf(6.0.68,4) = 0.3284...
(B) more than 4 couples,= 1 - binomcdf(6,0.68,4) = 0.67158...
(C) at most 4 couples. = binomcdf(6,0.68,4) =0.621977...
