**Objective:** Students will be able to write a definition of theoretical and experimental probability.

**Materials:** Large bag of M and M’s and 1 brown lunch bag per group

**Procedure:**- Students should be in groups of 3

- Each group should have one bag and a pile of colored candies.

- The group should count the number of each colored candy and record the data.

- The group should then record the number of times they predict that they will randomly select each color in as a fraction, decimal and percent.

- One member of the group should draw some of the candies from the bag, and the group should record the experiment on the tally sheet.

- The candies should be replaced, and the bagged gently shaken to mix the colors.

- The same procedure should be followed for 20 draws.

- Each group should then record their results on the chart of what actually happened. The results should be written as a fraction, decimal, and percent.

**Conclusions:** Students should answer the questions as a group at the end of the worksheet.

- Compare and contrast your predicted outcomes and your actual outcomes.

- Your predicted outcome is theoretical probability. Write a definition of theoretical probability.

- Your actual outcome is experimental probability. Write a definition of experimental probability.
