Here is this Monday's question:
You're in a dark room with 50 quarters, 18 of which are heads up. You are allowed to move around the coins or flip some or all of them, if you wish. Problem is, it's too dark to tell what you're moving or flipping (no, you can't figure it out by touch either). Your job is to split the coins into two groups, each of which has the same number of heads up coins. How do you accomplish this?Post your answers in the comments field. I will post the correct answer when I figure it out.
Note to George: This is the question I called you about on Saturday. Thanks for calling me back after "a few minutes."
