In probability and statistics, a probability mass function is a function that gives the probability that a discrete random variable is exactly equal to some value. Sometimes it is also known as the discrete density function. The probability mass function is often the primary means of defining a discrete … Ver más A probability mass function of a discrete random variable $${\displaystyle X}$$ can be seen as a special case of two more general measure theoretic constructions: the distribution of $${\displaystyle X}$$ and the Ver más Two or more discrete random variables have a joint probability mass function, which gives the probability of each possible combination of realizations for the random variables.
