Julie mistakenly calculated the conditional relative frequency for college students who like comedy as being 70%. What did Julie actually calculate, and what is the correct answer?

A. She calculated the joint relative frequency for college/comedy. The correct value of conditional relative frequency for college students who like comedy is 28%.

B. She calculated the conditional relative frequency for comedy films that are liked by college students. The correct value of conditional relative frequency for college students who like comedy is16%.

C. She calculated the conditional relative frequency for comedy films that are liked by college students. The correct answer is 28%.

D. She calculated the joint relative frequency for college/comedy. The correct answer is 16%.
