The probability of a basketball player hitting a foul shot is one-third. How many shots would you expect her to make in 90 attempts?

1/3 of her try will be a foul i.e. 90x1/3 = 30. so 30 attempts are foul. the remaining 60 attempts would be her best shot...

hope that helps..

It would be 30 because that is 1/3 of 90

30 shots is how many she wouldn't make, since 1/3 is how many she misses. If she makes 90 shots, and misses 1/3, (30) then she would score 60. Bonjo is correct

To find out how many shots we would expect the basketball player to make in 90 attempts, we first need to determine the expected value.

The expected value (often denoted by E(X)) is calculated by multiplying the probability of each outcome by the value of that outcome, and then summing them all up.

In this case, the value of a successful foul shot is 1, and the probability of making a shot is 1/3.

So, the expected value for a single shot is: (1/3) * 1 = 1/3.

To find the expected number of successful shots in 90 attempts, we multiply the expected value of a single shot by the number of attempts:

Expected number of successful shots = (expected value per shot) * (number of attempts)
= (1/3) * 90
= 30.

Therefore, we would expect the basketball player to make approximately 30 shots in 90 attempts.
