Solution
The geometric distribution formula is used to calculate the probability of the first success on the nth trial. In this case, we want to find the probability that the first successful three-point shot (a "success") occurs on the third attempt.
The formula for the geometric distribution is:
P(X = n) = q^(n-1) * p
where:
- P(X = n) is the probability of the first success on the nth trial,
- q is the probability of failure (1 - p),
- p is the probability of success,
- n is the number of trials.
Given that the player's accuracy rate is 25%, we have p = 0.25 and therefore q = 1 - p = 0.75. We're looking for the first success on the third attempt, so n = 3.
Substituting these values into the formula gives:
P(X = 3) = 0.75^(3-1) * 0.25 = 0.75^2 * 0.25 = 0.5625 * 0.25 = 0.140625
Rounding to the hundredths place gives 0.14. So, the probability that the basketball player makes his first three-point shot on the third attempt is approximately 0.14.
Therefore, the correct answer is a.) 0.14.

When shooting two free throws, the chance that a basketball player makes her first free throw is 70%. If she makes her first free throw, her confidence goes up and there is a 75% chance that she will make her second free throw.
