1. Teacher Note You will be playing the Gee Whiz Everyone Wins Game.
You will need a box or bag of colored blocks or tiles with the suggested ratio of 9 reds, 6 yellows, and 3 blues. The blocks should be hidden inside the container.

5. Discussing the Game What do you think random means?
A process of selecting or choosing so that each outcome has the same chance of being chosen.
Suppose you’re a member of the audience watching Gee Whiz Everyone wins. Would you rather be called to the stage first or last? Explain.
Last is better, because you can see what results all the other players get before you have to make a choice.
Does it matter that the block is returned to the bucket and the bucket is shaken after each contestant? Explain.
Yes, if the block isn’t returned then the number of blocks of that color is reduced. So, the probability of that color is reduced.

6. HINT: Take the number drawn of each color, and divide it by the total number of blocks drawn.

7. P (red) = 9/18 or 1/2
P (blue) = 3/18 or 1/6
P (yellow) = 6/18 or 1/3
9/18 + 3/18 + 6/18 = 18/18 or 1 Whole

8. Yes, there are 18 blocks, and each has the same chance of being chosen.
No, since there are 9 red blocks, there is a far greater chance of choosing a red on than there is of choosing a blue one.
