Dice and coin tosses – experimental probability

MathematicsProbabilityAges 11–12

Roll a die or flip a coin many times; each outcome is tallied in a table and a frequency bar chart updates instantly. Students compare the experimental probability (number of times an outcome occurs divided by the total number of trials) with the theoretical probability of 1/6 or 1/2, and watch the two values converge as the number of trials grows.
