## Experimental Probability

September 10, 2009We did an activity that worked really well today — for experimental probability, we gave each of them a spinner (some had 3 colors, some had 4, some had 4 in odd arrangements) and had them conduct 30 trials. Then, they switched spinners with someone and did 30 more trials. For each set, they figured out the experimental probability for each color. They seemed to understand it pretty well, and almost all of them got finished.

Based on their response, I think we should revise the form to list the colors and their totals, and to compare the experimental probability with the theoretical probability.
