Kollossal Airways and Teeny Weeny Airlines compete for passengers from Pointaye to Pointbee. It is known that each passenger who makes reservations fails to show up with probability $1 / 10$ independently of other passengers so Kollossal always books 20 passengers for their 18 seat airplane and Teeny books 10 for their nine-seat airliner. What is the probability that each is overbooked on a randomly chosen flight?

Key Concepts

Binomial Distribution

The binomial distribution models the number of successes in a fixed number of independent trials, each with the same probability of success. This concept is crucial when analyzing situations where there are discrete outcomes, such as a passenger showing up or not showing up for a flight.

Overbooking Strategy

Overbooking is the practice of accepting more reservations than available capacity, based on the likelihood that some reservations will not result in occupancy. This key idea involves calculating the probability that the actual number of attendees exceeds the available seats, helping organizations manage risks and optimize revenue.

Independence of Events

The assumption that each event (such as a reservation resulting in a no-show) occurs independently is fundamental for applying the binomial distribution. This means that the outcome of one passenger's decision does not affect the outcome of another's, allowing for straightforward probability calculations using multiplication rules.
