A Real TI-83 Craps Simulation Teaches Beginning Probability

Authors: Timothy W. Jones

Simple craps, a Vegas casino game, is easily modeled using a TI-83's programming, list, and statistics features. Roll two dice. If the coming out roll, as it is called is 2, 3, or 12, the player immediately loses. If a 7 or 11 is rolled, they immediately win. If any of the remaining totals are rolled, if the player rolls that number before rolling a 7, they win, not they lose. A program can be initialized with a bank roll and a standard, non-changing bet. Using the list feature 999 rolls, the maximum size of a list, can be stored in a built-in list. A bar chart for the distribution of numbers is easily generated and confirms the calculated probabilities. The code to mimic the game is straight-forward. The user repeatedly plays the game until the stake is 0, an inevitability given say a stake of $100 and a bet of $5. This certainty instills the truth: it's a loser's game.
