A function or rule that assigns a numerical value to each simple event of an experiment is called:
A)a sample space.
B)a probability distribution.
C)a random variable.
D)None of these choices.

Quizplus · Accepted Answer

A random variable is a function that assigns a numerical value to each simple event of an experiment. It is often used to describe the possible outcomes of a random process, and its distribution gives the probabilities of the different values that the variable can take. A sample space is the set of all possible outcomes of an experiment, while a probability distribution describes how the total probability of 1 is distributed among the possible outcomes. Therefore, B is not the best choice, and D is not a valid answer.
