Theoretical Probability of Repeated Experiments: Sample FAST Questions

Theoretical probability in 8th grade means counting favorable outcomes out of a full sample space for a repeated experiment, like the chance of rolling two even numbers or getting exactly one head in three flips. Answers can be written as a fraction, a decimal, or a percent.

How the FAST tests this benchmark

On the FAST, students answer multiple choice items and equation editor items entering a probability, usually as a fraction. Equivalent forms are accepted, but the sample space has to be counted first, and the favorite distractor is the single-trial probability.

Skills students need

Find the theoretical probability of an event in a repeated experiment
Count favorable outcomes within a sample space
Express a probability as a fraction, decimal, or percent
