Question 1

Answer 1

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:

$E(X) = np$

In this question:

$n = 48, p = 0.44$

Mean:

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

The mean is 21.12.
