2.1 Homework
Another popular game at the school carnival is a
spinner game called Making Purple, similar to the
game we played in Investigation 1.3. To play the
game, a player spins the pointer of each spinner
below once. If a player gets a red on one and a
blue on the other, the player wins because red and
blue together make purple.

purple on a turn.
C. How does the theoretical probability of making purple compare with the experimental probability of
making purple?
D. The cost to play this game is $2.00. The winner gets $6.00 for making purple. Suppose 36 people
play the game.
