Question

What rule of probability permits you to obtain any probability for a discrete random variable by simply knowing its probability distribution?

Short answer

$P(X\in R)-\sum _{x\in R}^{}P(X=x)$

Step-by-step solution

Step 1. Given information

Take occurrences that are mutually exclusive.

Step 2. Solution

The likelihood of a discrete random variable X taking a value from a set of real numbers.

If R is a positive number, then the probability of that variable is equal to the sum of the individual probabilities.

across the values ofthe collection of random variables

As a result, the above rule is applied to determine the probability of a discrete random variable.
