It's To Be Expected

Activity Overview

Students use a tree diagram to find theoretical probabilities and use this information with lists to find the expected value.

Objectives

  • Students will explore tree diagrams and expected values.
  • Students will be asked to differentiate between independent and dependent events, as well as combining probabilities.
  •  Students will try to make a connection with how to understand these topics in IB Mathematics courses and on their final assessments

Vocabulary

  • Expected Value
  • Tree Diagrams
  • Probabilities

About the Lesson

In this activity, students will use a tree diagram to find theoretical probabilities and use this information in lists to find the expected value. Students will be asked to differentiate between independent and dependent events and how to navigate the handheld when finding these probabilities. 

*Note: This activity includes optional IB support, including the IB Questions download for students who are preparing for the IB Exam.
