Need help with a simulation from CPM- Exponential decay

Hi TinkerPlotters,
I'm wondering if anyone has already created a simulation for the "Penny Lab" from CPM. Here is a short description:
1) Students start with 100 pennies.
2) They shake them up in a cup and pour them on the table.
3) They remove all of the "heads up" pennies.
4) They put the remaining pennies back into the cup and repeat the process until no pennies are left.
They then graph the data on an overhead and then the teacher layers the overheads to show the overall trend. Then we write a theoretical equation to represent the experiment.
I don't know how to handle this sort of recursion with TP.
Thanks for the help!
Jeff
