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

Short Answer

Expert verified

P(X鈭�R)-鈭�x鈭�RP(X=x)

Step by step solution

01

Step 1. Given information

Take occurrences that are mutually exclusive.

02

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.

utilizing the probability distribution of the variable
