In probability theory, expected value (also known as mathematical expectation, or mean) is a fundamental concept that helps us understand the average value of a random variable. It is used in various fields, including statistics, finance, and decision-making. In this article, we will explore the concept of expected value, its applications, and how to calculate it in different scenarios.
Expected value, in essence, is a weighted average of all possible outcomes of a random variable, with each outcome weighted by its probability of occurrence.
