1) An airline finds that 4 percent of the passengers that make reservations on a particular flight will not show up. Consequently, their policy is to sell 100 reserved seats on a plane that has only 98 seats. Find the probability that every person who shows up for the flight will find a seat available. What do I know? What do I want to find out? What do I expect the answer to be? How do I go from what I know to what I want to find? Is the answer consistent with what I expected?

Step 1
- The probability that a passenger will not show up is 4% (0.04). - The probability that a passenger will show up is 96% (0.96). - The airline sells 100 tickets for a flight with 98 seats. Show more…

An airline finds that 4 percent of the passengers that make reservations on a particular flight will not show up. Consequently, their policy is to sell 100 reserved seats on a plane that has only 98 seats. Find the probability that every person who shows up for the flight will find a seat available. What do I know (for example, what is n, pi, and x)? What do I want to find out? What do I expect the answer to be? How do I go from what I know to what I want to find? Is the answer consistent with what I expected?

. An airline knows that 10% of the people holding reservations on a given flight will not appear. The plane holds 90 people. (a) If 92 reservations have been sold, find the probability that the airline will be able to accommodate everyone appearing for the flight
Airlines sometimes overbook flights. Suppose that for a plane with 50 seats, 55 passengers have tickets. Define the random variable $Y$ as the number of ticketed passengers who actually show up for the flight. The probability mass function of $Y$ appears in the accompanying table. (a) What is the probability that the flight will accommodate all ticketed passengers who show up? (b) What is the probability that not all ticketed passengers who show up can be accommodated? (c) If you are the first person on the standby list (which means you will be the first one to get on the plane if there are any seats available after all ticketed passengers have been accommodated), what is the probability that you will be able to take the flight? What is this probability if you are the third person on the standby list?
