**Grade 12: Exponential Dice**

We start with 50 dice. They are rolled repeatedly and each time all the sixes are removed until all the dice are gone. The students repeat this experiment many times. There is lots of variation but the data ought to provide an exponential decay process with multiplier 5/6.

We take the average of 10 trials and use a log plot to check this out. We get a pretty good straight line.
