Answer: The mean of this binomial distribution is 53.36.

Explanation:

We know that , the mean of this binomial distribution is given by :_

$\mu = np$

, where n = sample size or the number of possible trials .

p = probability of getting success in each trial.

We are given that , the probability of success in each of the 58 identical engine tests is p = 0.92.

i.e. n= 58

p=0.92

Then, the mean of this binomial distribution =
58*0.92=53.36

Hence , the mean of this binomial distribution is 53.36.
