Question

If you sum the probabilities of the possible values of a discrete random variable, the result always equals .

Short answer

If you sum the probabilities of the possible values of a discrete random variable, the result always equalsto 1.

Step-by-step solution

Step 1. Given information.

The given statement is:

If you sum the probabilities of the possible values of a discrete random variable, the result always equals .

Step 2. Explanation.

Discrete random variables are variables that have a predictable outcome due to random events.

This is a countable variable with probabilities ranging from 0 to 1.

There are two types of discrete random variables: finite and infinite.

The sum of discrete random variables' probability is always 1.
