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.
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:
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.
