This activity is designed for students to complete after learning about binomial distribution. The calculator activity gives students a real-life perspective on binomial distribution. Students will perform simulated free throw attempts using graphing calculators. They will tally how many free throws out of groups of ten that are made and repeat this experiment twenty times. The teacher will quickly tally the results for the entire class. (The included Excel spreadsheet can help you do this with great speed.) Students will compare and contrast their individual results, the class results, and the theoretical probabilities. Finally, students will calculate the theoretical probabilities for a worse free throw shooter, comparing and contrasting these probabilities with those of Eric Gordon.
• Each student or pair of students should have a TI-83 or TI-84 graphing calculator
• Each calculator should have PROBSIM (Probability Simulation) program loaded on it
*Instructions for downloading this program included in this activity download*
• (Optional) Microsoft Excel (to speed-up tallying of class results)
• Be sure that each student or each pair of students has a TI-83 or TI-84 graphing calculator
• Upload PROBSIM onto each calculator the day before doing this activity by following the instructions on the Calculator Upload section of this file.
• Read the Teacher Instructions in the answer key section of this file to help you guide students through the activity & avoid common hang-ups.
