An airplane has 100 seats for passengers. Assume that the probability that a person holding a ticket appears for the flight is 0.90. If the airline sells 107 tickets, what is the probability that everyone who appears for the flight will get a seat?

Step 1
This is equivalent to 1 minus the probability that more than 100 passengers show up. The number of passengers who show up follows a binomial distribution with parameters n = 107 (the number of tickets sold) and p = 0.90 (the probability that a ticket holder shows Show more…

An airline sells 100 tickets for a certain flight on an airplane that has only 97 seats because, on the average, 2 percent of purchasers of airline tickets do not appear for the departure of their flight. Determine the probability that everyone who appears for the departure of this flight will have a seat.

The probability that a person who booked a flight will actually show up is 0.96. If the airline books 103 people on a flight for which the maximum capacity is 100, what is the probability that there will be not enough seats for everyone who shows up? Round your answer to 3 decimal places.

Each of the 100 people has made a reservation (for a flight, appointment, etc.). Each independently has a 97% probability of keeping it ("showing up"). What is the probability that at least 1 of the 100 will not show up?
