(PS10) Probability Mass Functions

This video builds on a basic introduction to probability by focusing on the different types of random variables: categorical, discrete, and continuous, and outlines the key properties of their probability mass functions (PMFs) and probability density functions (PDFs). We start with an in-depth look at PMFs, providing clear examples of basic calculations. We then introduce the concepts of expected value, nth moments, and variance, specifically within the discrete setting, and explain how these statistical measures are used to summarize and interpret data. Additionally, the session delves into Bernoulli random variables, a fundamental discrete distribution, where we derive and discuss its PMF and associated properties.
