Discrete Random Variables Random Variables A random variable is a variable whose value is determined by the outcome of an experiment. For example, if we let F be the random variable.

The risk of an investment is often measured by the standard deviation of the return on the investment. The more variable the return is, the riskier the investment. We can measure the great risk.
