Predictions & Solutions Involving Theoretical Probability

T.i.P.S.

Lightbulb
Students will use theoretical probability to make predictions and determine solutions for simple and compound events. Theoretical probability involves the likelihood of an event occurring that is predicted by using formulas and mathematical calculations without conducting an experiment. 

Example

Lyle and his siblings are playing a game involving a spinner during Family Game Night. Using the spinner below, how many times would Lyle and his siblings expect to land on the letter ”B” if they spin 128 times?
