📋 Teacher Answer Key
1. experimental
2. theoretical probability
3. 9/20
4. A small number of trials can vary a lot, so the results may not yet be close to the expected probability
5. 1/6
6. red appears 18 times in 20 spins when the model says 1/4
7. More trials usually make the experimental results more stable and easier to compare with the theoretical model
8. theoretical
