Math in Real Life - Why Airlines Overbook Flights

I'm currently flying home the ESC-20 Library Resource Roundup in San Antonio, Texas. Before I boarded the flight the gate agent was looking for volunteers to take an alternate flight due to overbooking. This seems like a good time to share the TED-Ed lesson Why Do Airlines Sell Too Many Tickets?

In Why Do Airlines Sell Too Many Tickets? students can learn about the mathematics that airlines use to maximize the revenue that they can generate from each flight. That math includes calculating the probability that everyone who holds a ticket for a flight will actually show up for the flight. The way that probability is calculated is explained in the video. Finally, the lesson asks students to consider the ethics of overbooking flights. Watch the video below or go here to see the entire lesson.
