This document provides instructions for conducting a coin toss probability experiment using a TI-Nspire calculator. It outlines the steps to create a spreadsheet with a random number formula to simulate coin tosses, copy the formula down 50 rows, and then create a statistics window and bar graph to analyze the results. The experiment allows students to visualize probabilities of heads or tails from repeated random coin tosses.
