The rules are simple. Choose a briefcase. Then as each round progresses, you must either stay with your original briefcase choice or make a "deal" with the bank to accept its cash offer in exchange for whatever dollar amount is in your chosen case.

Creating a Spinner to Examine Experimental and Theoretical Outcomes
Simulating the Spread of a Wildfire Using Probability
Create a game spinner with variable sized sectors to look at experimental and theoretical probabilities. Parameters: Sizes of sectors, number of sectors, number of trials.

Experiment with probability using a fixed size section spinner, a variable section spinner, two regular 6-sided dice or customized dice.

In this applet you can adjust the parameters on two Gaussian curves to determine if there is a possibility of a difference between the two means.

Create a game spinner with one to twelve sectors in order to look at experimental and theoretical probabilities. Parameters: Number of sectors, number of trials.

Concept with Explanation
Selected Homework from ACE

The unit How Likely Is It? was created to help students:

  • Understand that probabilities are useful for predicting what will happen over the long run

  • Understand the concepts of equally likely and not equally likely;

  • Understand that a game of chance is fair only if each player has the same chance of winning, not just a possible chance of winning;

  • Understand that there are two ways to build probability models: by gathering data from experiments (experimental probability) and by analyzing the possible equally likely outcomes (theoretical probability);

  • Understand that experimental probabilities are better estimates of theoretical probabilities when they are based on larger numbers of trials;

  • Develop strategies for finding both experimental and theoretical probabilities; and

  • Critically interpret statements of probability to make decisions or answer questions.
