Prior student knowledge should include calculation of theoretical and experimental probabilities, and the following vocabulary: trial, outcome, experiment, fair game and unfair game (for Benchmark MA.7.P.7.1).
The number of trials can be set from 1 to 9999 allowing students to make predictions about the outcomes and probability. These predictions can lead to the observation that as the number of trials increases, the experimental probability approaches the theoretical probability.
The coin flipping experiment can also be made unfair by changing the theoretical probablity from .5, which addresses Benchmark MA.7.P.7.1.
Extension questions are provided.
