The Conditional Probability Mass Function

This is a video in the "Introductory Probability" series. In it, we discuss the conditional probability mass function, and how it is formed in relation to the joint and marginal probability mass functions. Because of the relationship between the joint, conditional, and marginal distributions, we can move in both directions, either going from the joint to the conditional and marginal distributions, or else, from the conditional and marginal distributions to the joint. The joint distribution carries more information than the conditional or marginal, however, the conditional distribution tends to be easier to work out, directly.
