👉 The cumulative distribution function (CDF) is a mathematical function that describes the probability of a random variable falling within a range or interval. It measures the probability of an event occurring more than once. In other words, it's like the "probability" of all possible outcomes that fall between two points in a continuous space. This function is used to calculate probabilities for a wide variety of distributions, such as normal, binomial, and Poisson random variables. CDFs are often represented by symbols like f
