Question

Suppose that a variable has a binomial distribution with n=18 and p=0.48 what is the expected value of the variable?

Answer 1

8.64

Step-by-step explanation:

The expected value for a binomial distribution is equal to

E = np

Where n is the number of trials and p is the probability of success. In this case, n = 18 and p = 0.48. Then, the expected value is

E = (18)(0.48)

E = 8.64

Therefore, the answer is 8.64
