Students learn how to work out the probability of mutually exclusive events.

As learning progresses probabilities are given in the form of fractions, decimals and percentages in probability tables.

**Differentiated Learning Objectives**

- All students should be able to understand that mutually exclusive events have a sum of one.
- Most students should be able to calculate the probability of one event when the other is known if both are mutually exclusive.
- Some students should be able to calculate probabilities of mutually exclusive events using tables.
