Algebra II: Birthday Problem

Objectives

• Describe how sampling a population with N objects works
• Use the complement of an event to determine probability of an event not occurring

Vocabulary

• event
• series
• probability

About the Lesson

This lesson involves investigating the probability of two people having the same birthday in a crowd of a given size. Topics covered include basic probability theory, sampling distributions and infinite series approximations. As a result, students will:

• Be able to use probability to determine the likelihood of two people having the same birthday in a crowd of a given size.
• Be able to justify the probability of two people having the same birthday.
