Exactly 32% of the students in a school play a sport. Fifty students are selected randomly to determine the probability that, at most, 15 students play a sport. Should a binomial probability density function or cumulative distribution function be used? Explain. (2 points) A) A binomial cumulative distribution function should be used because the question states exactly 32% of students play a sport.

B) A binomial probability density function should be used because the question states exactly 32% of students play a sport.

C) A binomial cumulative distribution function should be used because the question asks for determining the probability that, at most, 15 students play a sport.

D) A binomial probability density function should be used because the question asks for determining the probability that, at most, 15 students play a sport.

E) A binomial probability should not be used because the events are not independent of each other.
