    2. 2 7.2 Random Variables and Probability Distributions A random variable is a function or rule that assigns a numerical value to each simple event in a sample space. A random variable reflects the aspect of a random experiment that is of interest for us. There are two types of random variables: Discrete random variable Continuous random variable.

    3. 3 A random variable is discrete if it can assume a countable number of values. A random variable is continuous if it can assume an uncountable number of values.
