difficult planning

Lester is responsible for the utilisation analysis of a large airline.

After a large evaluation, he notes that only about 89% of all tickets booked are also used on routes that are mainly used by business people. This means that 11% of all tickets booked on these routes are unused, so that even in booked aircraft seats remain free. A strong piece.

The airline therefore wants to launch a pilot project on a route to optimize the taking situation. The route is flown by an aircraft with 150 passenger seats

Task 1:

Calculate the probability that the aircraft is fully occupied on a flight (all tickets have been sold).

From this result, Lester concludes that it is a good idea to sell just more tickets than places are available. He’s a crazy boy.

Task 2:

Describe the negative consequences for the airline from Lester’s plan.

Calculate the probability that the negative consequences will occur when the airline sells 160 tickets for the flight.

Task 3:

Calculate the number of seats required in the aircraft so that a space can be made available to all 160 ticket owners with a probability of 99%
