Question

You and a friend are working on shooting free throws at basketball practice. Your friend has a season average of making 80% of his shots. What is the probability that your friend is doesn't make a shot until his 5th attempt

Answer 1

Answer: The probability that his friend doesn't make a shot until his 5 th attempt is 0.00128.

Explanation:

Since we have given that

Probability of making his shot = 80%

Probability of missing his shot = 20%

We need to find the probability that his friend doesn't make a shot until his 5th attempt.

So, our required probability would be

`(0.20)^4(0.8)\\\\=0.00128`

Hence, the probability that his friend doesn't make a shot until his 5 th attempt is 0.00128.
