Students learn how to list all the permutations of two events and calculate their probabilities.

Later, as learning progresses sample space diagrams are introduced for the more able.

**Differentiated Learning Objectives**

- All students should be able to list all the permutations for two independent events.
- Most students should be able to list all the permutations for two events and find a probability.
- Some students should be able to calculate the probability of a combined event using sample space diagrams.
