The set of probabilities associated with the values in a random variable's sample space is called

Probability Distribution

Step-by-step explanation:

Probability Distribution determines the possibility that an outcome will occur in a random experiment.

The probability of a certain event is 1 and that of event that will never occur is 0.

The sum total of all probabilities of all outcomes in a random experiment is 1.

There are different types of probability distribution, namely: normal distribution, poison distribution, chi square distribution etc.

The distribution types are required for different purposes. For example, normal distribution estimates the probabilities of an outcome occuring for a given number of trials given the probability of each event in each trial.
