Students learn how to calculate a probability from a two-way table.

As learning progresses students learn how to create a two-way table from a written description and consider how the sample size changes for specific groups.

**Differentiated Learning Objectives**

- All students should be able to complete a two-way table.
- Most students should be able to use two-way tables to calculate theoretical probabilities.
- Some students should be able to understand the change in sample size for different criteria.
