At a County fair there is a spinner game with 12 sectors: 2 red sectors, 2 green sectors, 2 blue sectors, and 6 yellow sectors. If the spinner lands on a red sector, the player wins 2 tokens. If the spinner lands on a green sector, the player wins 2 tokens. If the spinner lands on a blue sector, the player wins 2 tokens. If the spinner lands on a yellow sector, the player loses 5 tokens.

Is this game fair for the player and how much will the player win or lose on an average over time? Explain.

Answer:

The expected value is -1.5, and the game is not fair. So the player will lose about 1.5 tokens for a single spin over time.
