Click the green flag, and enter the number of dice you want to be rolled. This project uses conventional dice( D6's), as well as 12- and 20-sided dice. Then enter the number of times you want this set of dice to be rolled. The project will record the sum of all the dice each time they are rolled, and the amount of each result is indicated by the height of the columns.
This project shows how symmetry will appear out of total randomness. It also shows that rolling different types of dice together does not affect where the peak probability is centered.
