[Free Registration/Login may be required to access all resource tools.] Define and calculate experimental probabilities.

The definition and properties of probability are given along with examples of how to find the probability of an event. Links are included for interactive probability games involving birthdays and the lottery.

In this tutorial, conditional probability is presented with a definition and examples.

This tutorial defines experiment, sample space, and event. Several examples are presented to help distinguish between them.

Explains the fundamental principle of counting, which is the beginning point for any study of counting techniques such as combinations and permutations.

This tutorial explains how to distinguish between independent and dependent events. Several examples are provided to find the probability of each type of event.

The instructional activity will explore counting, sorting, and graphing skills. The instructional activity provides young scholars an exciting and fun way of exploring and internalizing graphing, sorting, and counting skills....
