Expected Value and Fair Pricing

The video tutorial explains the concept of expected value and fair price using a raffle ticket example. It covers the formula for expected value, demonstrates how to calculate it, and discusses its implications in terms of gain or loss. The tutorial also explains how to determine a fair price to play a game, ensuring the expected value is zero, meaning no net gain or loss. The video provides detailed calculations and examples to illustrate these concepts.
