What about dice and probability?
When we use a die for a game, we want the die to be fair. What does it mean?
Suppose two players use a six-sided die that has the sides numbered 1,1,2,2,3 and 4. There are four numbers that can come up (1, 2, 3, and 4). Is the game fair if the first player wins when 1 or 2 shows, and the second player wins if 3 or 4 shows?
Even though each player has two winning numbers, these numbers are not equally likely! Can you come up with more examples of games where numbers are or aren't equally likely to be chosen?
