# Lesson Plan: Expected Values of Discrete Random Variables Mathematics • 10th Grade

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to calculate the expected value of a discrete random variable from a table, a graph, and a word problem.

#### Objectives

Students will be able to

- calculate the expectation value of a discrete random variable from a table,
- calculate the expectation value of a discrete random variable from a graph or a word problem describing a real-world system.

#### Prerequisites

Students should already be familiar with

- discrete random variables,
- the probability distribution function of a discrete random variable.

#### Exclusions

Students will not cover

- standard deviation,
- variance,
- continuous probability distributions,
- properties of expectation values (i.e., ).
