### Theoretical Probability :

Theoretical Probability Objective: Apply theoretical probability to predict, compare, and replicate experiments.

### Slide 4:

Vocabulary Outcome – a possible result of an experiment. Sample Space – The set of all possible outcomes. Theoretical Probability – a comparison of the number of favorable outcomes to the number of possible outcomes.
