The Probability Mass Function (PMF) is a fundamental concept in probability theory that describes the probability distribution of a discrete random variable. It provides the probability of each possible outcome or value that the random variable can take on. The PMF is a crucial tool in understanding and analyzing discrete probability distributions, such as the Geometric and Exponential distributions, which are important topics in introductory business statistics courses.
