Answer:

The mean is 21.12.

Explanation:

Binomial probability distribution

Probability of exactly x successes on n repeated trials, with p probability.

The expected value of the binomial distribution is:


E(X) = np

In this question:


n = 48, p = 0.44

Mean:


E(X) = np = 48(0.44) = 21.12

The mean is 21.12.
