Here are the rules of a game. Each person chooses heads or tails at random, then a coin is thrown.
People who choose the side shown by the coin are left in the game.
The rest are out of the game.
If a group of 1000 people are going to play this game, how many people might you
expect to be left in the game after 5 throws?
