Assume that each of the n trials is independent and that p is the probability of success on a given trial.muse the binomial probability formula to find P(x).

n = 5, x= 2, p= 0.3

P(x) = Round to four decimal places

Solution

X is binomial with n =5 p =0.3

P(X=2) = 5C2(0.3)²(0.7)³

= 10(0.09)(0.343)

= 0.3087
