How many ways can you split 12 people into 3 teams of 4? WebAug 12, 2024 · Discrete distributions can be laid out in tables and the values of the random variable are countable. These distributions are defined by probability mass functions. The probability mass function (or pmf) calculates the probability that the random variable will assume the one specific value that it is being calculated at: Pr(X=a).
