7. Probability in Birthday Parties

• In the game twister we are using probability to see our
chances:

red, blue, green, or yellow is ¼ or 1 out of 4
• Players take a chance of falling with each movement to a
new spot.
8. Pizza at Birthday Parties

commonly divided into 8
triangular slices. When you
divide the pizza this way, each
person receives 1/8 of the
pizza.
• If you eat 4 slices of the pizza, it
is equivalent to eating ½ of the
entire pizza.

11. Algebra
