You can put this solution on YOUR website! in a binomial situation n=4 and p=0.25 determine the probabilities of the following events using the binomial formula
a. P(x=2) = 4C2*(0.25)^2(0.75)^2 = binompdf(4,0.25,2) = 0.2109
------------------
b. P(x=3) = 4C3*(0.25)^3(0.75) = binompdf(4,0.25,3) = 0.0469
------------------
