Dice-Difference Game
The Game: We throw 2 dice - 1 Blue and 1 Green. What is the difference in values? The difference can be 0, 1, 2, 3, 4, or 5. I say to my friend: "I win if the difference is a 0, 1 or 2 and you win if it is a 3, 4 or 5. Each of us has 3 chances to win. Let's play!" Question: Would you play?

Guided Activity
Do the experiment 200-1000 times.
- Is my game fair?
- Which difference seems to happen the most often?
- Which difference seems to happen the least often?
Now for some dreaded theory ...
- Make a table with the value of the green die across the top row and the value of the blue die going down the first column and the difference between the values at their "intersection". Show me!
- Theoretically, how many possible combinations of dice can be thrown?
- Theoretically, how many of these combinations will have a difference of 1?
- How many ways can a difference of 5 happen?
- What percentage of times should 0 happen?
- Does this agree with your experimental results?
- What is the percentage of times that a 0, 1 or 2 occurs? How about a 3, 4 or 5?
