Simulate Rolling Dice with Many Trials
This activity simulates rolling dice and discarding all dice equal or less than a given number and repeating this process with the remaining dice until there are no more dice.
The number of trials lets you set how many times this process is repeated with the results graphed being the average across all of the trials.
I recommend trying this activity a few times with a different number of trials and with different numbers set for the roll to see what happens and to compare results.
