Historically, the probability that a customer will show up for a randomly selected reservation is 96%. 1. Assume that all 185 cars were booked. Let X be the number of reservations for which the customer showed up. a. Describe the distribution of X: X~ ?o (n=C],p=C]) b. Find the probability that there will be available cars at the end of the day, in other words, find the probability that not all customers will show up: P(X g D) 2 (Round the answer to 4 decimal places) c. Find the expected number of customers who show up to pick up a car: E[X] 2 (Round the answer to the whole number) d.
