Flipping for Dollars (Posted on 2002-10-09)

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?

If a person has $1000^x, then $5*x is approximately the fair admission price of the game.

If the admission price of the game is $100, then the person must have at least $1000^20 to play it. It is extremely doubtful whether even ELON MUSK has that amount of money.
