Generate one or more random numbers within a range that you define. Enter the minimum and maximum for the range you want and enter the number of numbers you want generated.

This site contains information on the randomness and geometric probability. It includes several links for information, includes real life examples.

This section of the Statistics Glossary offers definitions of terms having to do with random variables and probability distributions such as expected value and normal distribution.

An overview of the term "discrete random variable." The site continues with the definition "continuous random variable" so that the user may compare the two.

Describes random variable and briefly mentions the two types of random variables: discrete and continuous.

An overview of the term "continuous random variable." The definition follows immediately after "discrete random variable" so that the user may compare the two.

Compute the expected value given a set of outcomes, probabilities, and payoffs. Students receive immediate feedback and have the opportunity to try questions repeatedly or receive hints.
