Penny Problem (Posted on 2003-10-14) Difficulty: 3 of 5
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?

If your given is 128 pennies head up. Then count out 128 pennies and then the rest will be heads down. you don't have to see to count. count out 128 pennies, then count the rest. you may not have the right ones heads up tales up but the math WILL be right.!!
