A probability mass function (PMF) is a function that describes the probability of discrete random variables taking specific values. It assigns probabilities to each possible outcome of a discrete random variable, providing a summary of the likelihood of different values occurring. The PMF is often denoted as P(X = x), where X is the random variable and x is a specific value it can take.
