# If x is a random variable, what properties must Pr(x) satisfy to be a discrete probability distribution function?

To determine

The properties that must Pr(x) satisfy to be discrete probability distribution function if x is a random variable.

Explanation

Given Information:

x is a random variable.

Explanation:

A probability of a discrete random variable x is known as discrete probability distribution if it satisfies the condition that for any value of x the probability must be 0Pr(x)1 and the sum of all probability must be 1.

Thus, for each value of x,

The probability must be greater than or equal to 0. The probability cannot be negative.

This implies, Pr(x)0
