# Statistics: Makin' It Through The Winter

by Texas Instruments - Bell Ringer Lesson

#### Overview

Students simulate a binomial distribution and calculate probabilities for a variety of situations involving binomial probability distributions.

#### Key Steps

• Students investigate a binomial distribution of the survival rate of Emperor penguin eggs by creating a list of 50 simulations using the Random Binomial, randBin, command. This effectively simulates data with a given probability of success. Then students will sort the data to determine the experimental probability for a given number of eggs surviving.

• Students calculate theoretical probabilities of a single event using both a formula and the Binomial Distribution Probability, binompdf, command.

• Students calculate theoretical probabilities for at least and at most of a specific x-value using the Cumulative Binomial Probability, binomcdf, command. For example, the probability that at least 25 eggs hatch. They will also calculate the expected value.
