In this lesson, we will talk about marginal probability. Marginal probability is kind of a tool that you use in the service of calculating conditional probability and conditional expectation. We do have another video that comes after this one where you will see this being used in the service of conditional probability and conditional expectation. In this video, we are just going to learn what marginal probability is. We will learn how to calculate it, and we will practice it with some examples. Marginal probability is something you can talk about with discrete probability or with continuous probability.
