#### Activity Overview

If you simply guess how well can you actually do on a multiple-choice quiz? Use nonsense questions with randomly-generated answers to help students compare experimental probabilities with expected theoretical probabilities.

#### Before the Activity

Give the students the following scenerio: You walk into your math class and panic, because all the people in the class are speaking Gobbledygook. You cannot understand a word anyone is saying, and absolutely nothing is making sense. The teacher passes out a quiz. You can see that there are 10 problems on the quiz, and you can see that it's a multiple choice quiz. Other than that, you are completely clueless. You decide to simply guess on every problem on the quiz and hope that you will get at least a 60%.

#### After the Activity

After collecting the students' answers, use the powerpoint feature to discuss the results. Possible discussion topics: (1) Did anyone get 100%? (2) Did anyone get 0%? (3) How closely did our experiment match what we had predicted?
