Answer:

The mean is 21.12.

Step-by-step explanation:

Binomial probability distribution

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

The expected value of the binomial distribution is:

[tex]E(X) = np[/tex]

In this question:

[tex]n = 48, p = 0.44[/tex]

Mean:

[tex]E(X) = np = 48(0.44) = 21.12[/tex]

The mean is 21.12.
