Final answer:
The probability of Tim Duncan making all of his next 8 free throw attempts can be calculated by multiplying the probability of making a single free throw (0.72) by itself 8 times.
Step-by-step explanation:
The probability of Tim Duncan making all of his next 8 free throw attempts can be calculated by multiplying the probability of making a single free throw (0.72) by itself 8 times. This is because the probability of making each free throw is independent and does not change based on previous outcomes. Therefore, the correct answer is (a) 0.72²⁸.
