------------------------------------------------ Marcy makes 15 out of 20 free throws at basketball practice. What is the probability that she will miss her free throw?

A. 1/2
B. 3/4
C. 2/5
D. 1/4

Answer :

Answer:

D. 1/4

Step-by-step explanation:

You want to know the probability Marcy will miss a free throw, given that she makes 15 of 20.

Probability

We assume Marcy's record at practice is typical of her performance. It tells us that she makes 15/20 = 3/4 of the free throws she takes. That means she misses 1 -3/4 = 1/4 of the free throws.

The probability she will miss her free throw is 1/4.

Additional comment

Many assumptions are involved in this calculation. One of them is that her next throw is unaffected by her last throw. It is a rare player for whom that is the case.
