Question

John's average for making free throws in a basketball game is $0.8$. In a one-and-one free throw situation (where he shoots a second basket only if he makes the first), what is the probability that he makes exactly one basket?

Answer 1

He gets two baskets but only makes one. In fraction form that is 1/2 and since there are there possibilities making both, making one and making none there is 1/3 of a chance of him making one basket.
