Flipping for Dollars (Posted on 2002-10-09) Difficulty: 3 of 5
We play a game as follows:

I place one dollar on the table. I repeatedly flip a coin. Each time the coin comes up heads, I double the money on the table. The first time the coin comes up tails, you take the money and the game is over.

What's a fair admission price for the game?

Would you play the game with me for $100?

I guess it wasn't clear.


You pay me to enter the game. Once you've paid (and I've pocketed your money), I put $1 on the table and begin flipping.


So, I invariably get whatever amount we agreed is the price of the game. You get a variable amount, depending on the outcomes of the flips. You always get at least $1.
