# Lesson Plan: Operations on Events: Difference Mathematics

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to find the probability of the difference of two events.

#### Objectives

Students will be able to

• understand and use notation for the difference between two sets ,
• understand the difference rule for probability:
• ,
• ,
• use the difference rule and other rules for operations on events to calculate probabilities involving the difference between two events (including their complement),
• use the difference rule along with other operations on events to solve problems in context.

#### Prerequisites

Students should already be familiar with

• the probability of simple events,
• dealing with fractions and percentages,
• operations on the complement, intersection, and union of events.

#### Exclusions

Students will not cover

• the probability of compound events,
• conditional probability,
• Bayes’ theorem.
