## In It to Win It!

#### Activity Overview

Students calculate the experimental probability of winning a basketball game by shooting two free-throws using a random integer simulation.

#### Key Steps

• A 70% free throw shooter is at the foul line with no time left on the clock. What is the probability that she will make both free throws to win the game?

• For the second problem, students will investigate the famous problem – if there are 25 unrelated people in a room, what is the probability that two of them will share a birthday?

• In the extension, students will use what they’ve learned from Problems 1 and 2 to calculate the experimental probability of a batter walking to first base, given the percentage of strikes that the pitcher throws.
