0 Question 8 ' Assume that an airline operates a 117-seat Airbus A318 on a particular route. Historically, the probability of a passenger showing up for a flight is 98%. 1. Assume that 117 tickets were sold. Let X be the number of passengers who showed up for the flight. a. Describe the distribution of X: X~ BC (n= .,p= I) 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 g D) = D (Round the answer to 4 decimal places) c. Find the expected number of passengers who show up for the flight: E[X] = D (Round the answer to the whole number) d. Find the expected number of empty seats by subtracting the E[X] from the plane capacity: C] (Round the answer to the whole number) 2. Assume that the airline sells 1 more ticket( 5). Let Y be the number of passengers who showed up for the flight. a. Describe the distribution of Y: Y~ BC (n: D,p= D) b. Find the probability that more passengers will show up than the plane can carry: P(Y > D) = D (Round the answer to 4 decimal places) Question Help: E Video 1 [1'] Video 2 Q Written Example 1 8 Message instructor Submit Question Jump to Answer D Post to forum
