# Statistics: Is it Rare?

by Texas Instruments - Bell Ringer Lesson

#### Overview

Students use the Poisson distribution to determine the probabilities for various numbers of hurricanes hitting the United States in a given year.

#### Key Steps

• In this activity, students will determine the probabilities of various numbers of hurricanes hitting the United States using a Poisson Distribution. They will accomplish this using the Home screen and the List Editor.

• Then students will explore how the graph of the Poisson Distribution changes when the average number of hurricanes changes by creating a connected scatter plot of the probabilities vs. number of hurricanes.

• At the end of the activity, students are introduced to finding cumulative probabilities. They are also given additional exercises to complete own their on, either in class or as homework.
