Using the binomial distribution, considering that he scores between 13 and 15 points in 60% of his games, he is expected to score 13-15 points in 9 games out of the remaining 15.

For each game, there are only two possible outcomes, either he scores between 13 and 15 points or he does not. His score on a single game is independent of any other game, hence the binomial distribution is used to solve this question.

What is the binomial probability distribution?

It is the probability of exactly x successes on n repeated trials, with p probability of a success on each trial.

The expected value of the binomial distribution is:

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

In this problem:

  • There are 15 games, hence n = 15.
  • He scores between 13 and 15 points in 60% of his games, hence p = 0.6.

Then:

E(X) = np = 15 x 0.6 = 9.

He is expected to score 13-15 points in 9 games out of the remaining 15.
