Problem 2 Not long after being put into service, some electric scooters manufactured with a certain brand have developed cracks on the underside of their main frame. Suppose a particular college campus has 25 such scooters, and cracks have actually appeared in eight of them. a. How many ways are there to select a sample of five scooters from the 25 for thorough inspection? b. In how many ways can a sample of five scooters contain exactly four with visible cracks? c. If a sample of five scooters was chosen at random, what is the probability that exactly four of the five will have visible cracks? d. If scooters are selected as in part c, what is the probability that at least four of those selected will have visible cracks
