Welcome to Week 8 Lecture 4 of the course "Statistics for Data Science - I" by Prof. Andrew Thangaraj.

Video Overview
This lecture introduces the concept of Discrete Random Variables and explains how they are used to represent outcomes that take on a finite or countable number of distinct values. Using clear examples, we explore how Probability Mass Functions (PMFs) describe the probability associated with each possible value of a random variable. The lecture also discusses the key properties of PMFs, including how probabilities are distributed and how they must sum to one. Step by step examples are provided to strengthen understanding of PMFs and their role in probability theory.
