Binomial probability mass function
WebBinomial distribution probability mass function (PMF): where x is the number of successes, n is the number of trials, and p is the probability of a successful outcome. WebJun 9, 2024 · A probability mass function (PMF) is a mathematical function that describes a discrete probability distribution. It gives the probability of every possible value of a variable. A probability mass function can be represented as an equation or as a graph. Example: Probability mass function
