Assume that an airline operates a 90-seat Canadair RJ 900 on a particular route. Historically, the probability of a passenger showing up for a flight is 87%. 1. Assume that 90 tickets were sold. Let X be the number of passengers who showed up for the flight. a. Describe the distribution of X: X ~? v (n b. Find the probability that the flight is not full, in other words, find the probability that not all passengers will show up: P(X < (Round the answer to 4 decimal places) c. Find the expected number of passengers who show up for the flight: E[X] (Round the answer to the whole number) d. Find the expected number of empty seats by subtracting the E[X] from the plane capacity: |(Round the answer to the whole number) 2. Assume that the airline sells 6 more ticket(s). Let Y be the number of passengers who showed up for the flight. a. Describe the distribution of Y: ? v (n = b. Find the probability that more passengers will show up than the plane can carry: P(Y > (Round the answer to 4 decimal places) Assume that an airline operates a 90-seat Canadair RJ 900 on a particular route.
