Final answer:

The random variable X represents the number of football players picked from the nine athletes scheduled. The probability distribution of X can be calculated. The selection of athletes is done without replacement. So, the correct answer is option

Step-by-step explanation:

The random variable X represents the number of football players picked from the nine athletes scheduled to appear at the charity benefit.

b. The values that X may take on are 0, 1, 2, 3, 4, and 5.

c. The distribution of X is as follows:

P(X=0) = 1/495

P(X=1) = 9/495

P(X=2) = 36/495

P(X=3) = 84/495

P(X=4) = 126/495

P(X=5) = 99/495

The selection of athletes is done without replacement since once an athlete is selected, they are no longer available for selection.

So, the correct answer is option d.
