Question 1195764:
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.

You can put this solution on YOUR website! **a) Probability of a full scholarship for a recruit in a top conference:**
* Given:
* 75% of five-star recruits go to top three conferences.
* 93% of five-star recruits get full scholarships.
* Since the probability of getting a full scholarship is independent of the conference chosen (given in the problem), the probability of a five-star recruit in a top three conference getting a full scholarship is simply **93%**.
**b) Odds of a recruit NOT selecting a top three conference:**
* Probability of selecting a top three conference: 75%
* Probability of NOT selecting a top three conference: 100% - 75% = 25%
* Odds are typically expressed as a ratio of the probability of an event occurring to the probability of the event not occurring.
* Odds against selecting a top three conference:
* (Probability of NOT selecting) / (Probability of selecting)
* = 25% / 75%
* = 1/3
* Therefore, the odds of a randomly selected five-star recruit NOT selecting a university from one of the three best conferences are **1 to 3**.
**c) Independence and Inclusivity/Exclusivity:**
* **Independence:**
* The probability of a recruit getting a full scholarship is independent of the conference they choose. This is stated in the problem.
* **Inclusivity/Exclusivity:**
* The events "selecting a top three conference" and "not selecting a top three conference" are **mutually exclusive**. This means a recruit cannot simultaneously select a top three conference and not select a top three conference.
**In Summary:**
* a) Probability of a full scholarship for a recruit in a top conference: 93%
* b) Odds of a recruit NOT selecting a top three conference: 1 to 3
* c) Scholarship probability and conference choice are independent events.
* Selecting a top three conference and not selecting a top three conference are mutually exclusive events.
