Probability Distributions

Published on 08/29/2011

Activity Overview

Students list outcomes for probability experiments such as flipping a coin, rolling number cubes, and observing the sex of each child born in a family. They use these outcomes to record the values of random variables, such as number of tails, sum of the cubes, and number of boys. Students then create the histograms representing the distributions of the variable and complete a table listing the probabilities of each value.

Before the Activity

Download the attached PDF and look over the information on the first page. Download and distribute the attached .tns file and Student Worksheet for use during the activity. A .tns file containing expected student results is also available for download.

During the Activity

Discuss the material from the activity pages and worksheet with students as needed.

After the Activity

Encourage students to summarize what they have learned from completing the activity. If desired, discuss the extension with students.
