To foul or not to foul, that is the basketball question. High schoolers look at the probability that fouling out a player and allowing free throws yields a better outcome than allowing the original shot. The resource provides a...

Find the box with two green balls. The applet uses six balls, three green and three red, and hides them in three boxes. Pupils choose a box and click on it to reveal the color of balls inside. Using the chosen box, the simulation keeps...

Grab some marbles from a bag. The applet simulates drawing marbles from a bag. Pupils determine the number of four colors of marbles in a bag and how many marbles to draw. Using information on whether order matters in the draw and if...

Pupils roll a die to figure out which car advances on a race track. They determine the rules for each car moving forward and, given the statistics of the winner, compare if it matches their predictions.

Bring the concept of conditional probability alive by allowing your classes to explore different probability scenarios. Many tasks have multiple solutions that encourage students to continue exploring their problems even after a solution...

Probability, especially conditional probability, can be a slippery concept for young statisticians.  Statements that seem self-evident on the surface often require a daunting amount of calculations to explicate, or turn out to be...

This site from the Northern Illinois University gives general background information on probability and also includes books and other websites that contain information on Probability.

Find dependent probabilities like P(A | B) or P(B | A) for a variety of contexts. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

This lesson focuses on probability theory for predicting the outcome of flipping a coin, and then flipping it multiple times.

In this section, students will explore different methods for determining the probability of complex events and conditional probabilities (such as unions, intersections, and complements).
