Decaying Dice
This applet simulates rolling dice.
The first trial the applet simulates rolling up to the number of dice on the dice slider and removes any dice with a value equal to or less than the roll number. For example, the initial settings on the applet will roll 50 dice and remove all 1s or 2s that are rolled. In each subsequent trial, the applet continues rolling the remaining dice, continuing removing dice, until no more dice remain.
The applet then prints out the trial number followed by the number of dice rolled during that trial.
