This activity teaches the difference between theoretical probability and experimental probability: why things that happen in real life do not exactly match probability. Students first find the theoretical probability of landing on each color of a spinner, then use the spinner to conduct their own experiment. They learn that the results of the experiment are close the the theoretical probabilities, but not exact. Theoretical probability is an estimate; experimental probability is the actual result.
Following the experiment, students are given the opportunity to practice determining the experimental probability for various scenarios using data from several experiments. This activity is also a good review for practicing writing proabilities as fractions, decimals, and percents. An answer key is included!
