Penny Problem (Posted on 2003-10-14)

You are blindfolded before a table. On the table are a very large number of pennies. You are told 128 of the pennies are heads up and the rest are tails up.

How can you create two subgroups of pennies, each with the same number of heads facing up?

I haven't worked out the details but I bet it has something to do with selecting a certain number of coins and turning half od them over....
