Let's assume the following statements are true: Historically, 75% of the five-star football recruits in the nation go to universities in the three most competitive athletic conferences. Historically, five-star recruits get full football scholarships 93% of the time, regardless of which conference they go to. If this pattern holds true for this year's recruiting class, answer the following:

a. Based on these numbers, what is the probability that a randomly selected five-star recruit who chooses one of the best three conferences will be offered a full football scholarship?

b. What are the odds a randomly selected five-star recruit will not select a university from one of the three best conferences? Explain.

c. Explain whether these are independent or dependent events. Are they Inclusive or exclusive? Explain.

The problem above can be shown on a tree diagram as shown below

Question a)

Let C represents the five-star recruit who chooses one of the best three conferences

Let S represents the scholarship offer

P (C∩S) = 0.75*0.93 = 0.6975

Question b)

P (C'∩S) = 0.75*0.07 = 0.0525

Question c)

The two events are independent because it is possible for the events to happen in any order and one event's outcome does not affect the other event's.
