Units #2: Probability of Simple and Compound Events
Learning Goal:
Students will investigate chance processes and be able to develop, use, and evaluate
probability models.
Essential Question(s):
1. How do you determine the probability of an event and check for
reasonableness?
2. What is the relationship between experimental and theoretical probabilities?
Higher Order Questions:
