Go round and round to compare theoretical and experimental probabilities. Learners set the number of sectors and the number of spins for a spinner. Then, a table displays the experimental and theoretical probabilities of the spinner for...

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...

Wanna take a chance on which game is best? The resource provides three games of chance using multiple types of games. Games range from coin toss to cards. Choosing a type of game, pupils determine what wins and enter the theoretical...

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.

Spin into a dicey experiment. Pupils use a spinner or a pair of dice to determine the experimental probabilities of each outcome. The interactive allows for either, one, five, or ten consecutive experiments. Using the applet, learners...

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...

Roll the dice with this multimedia math lesson on probability. After first viewing a series of three short videos explaining probability, independent events, and dependent events, young mathematicians complete a set...

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, a number between 0 and 1 which describes the likelihood of a certain event. A probability of 0 means that something is impossible; a probability of 1 means that something is certain.

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

This section explores how to determine the sample space, or possible outcomes, for an event such as rolling dice. It also investigates how to determine the probability of different outcomes occurring for an activity such as flipping a...

Find a quick, concise explanation of probability. An example is given and clearly explained.
