For a discrete random variable A,the probability distribution of the discrete outcomes is called a ________.

A) conditional mass function,c(a)
B) cumulative frequency function,m(a)
C) probability mass function,f(a)
D) discrete value function,d(a)

The probability distribution of a discrete random variable A is called the probability mass function, denoted by f(a). This function assigns a probability to each possible value of A, such that the sum of probabilities over all possible values of A equals 1. Therefore, the best choice is C. The other options are either not applicable to probability distributions or do not accurately describe the probability distribution of a discrete random variable.
