Analyze this simple betting game with your math student. Discuss probability, the measure of how likely it is an event will occur, as you work to figure out whether the odds of successfully rolling the 3 numbers during the three rounds of play are in the player's favor. All you need is a set of three dice, and you can get rolling! Play several times and look for patterns in the game. Is the player likely to win? Take a close-up look at each round of the game.

• Three dice

### What You Do:

1. Select a dealer and a player. The object of the game is for the player to roll a 1, a 2, and a 3 during 3 rounds of rolling the dice.
2. If one of these numbers is rolled after the first or second round, they should put that die aside and not roll it again.
3. If the player succeeds in rolling a 1, 2, and 3, he wins.
4. Switch roles and play again.
5. After playing several times, start a discussion about probability, and what the chances are of rolling a particular number in each of the three rounds. Is the game fair? Who has the better odds, the dealer or the player?
