Makin' It Through The Winter #### Activity Overview

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

#### Key Steps

• Students begin by investigating a binomial distribution by using a simulation. They create a list of 200 trials using the Random Binomial command, effectively simulating data with a given probability of success. Then, students will graph the data with a quick graph to determine the experimental probability.

• Students calculate theoretical probabilities of a single event using the formula and the built-in handheld command, Binomial Pdf.

• Students calculate theoretical probabilities for ‘at least’ and ‘at most’ of a specific x-value using the built-in handheld command, Binomial Cdf.
