pdf Experimental Probability A

This worksheet provides meaningful practice comparing theoretical and experimental probability through spinner-based scenarios and data analysis. Students begin by reviewing the definitions of theoretical probability and experimental probability, reinforcing the distinction between predicted outcomes and actual results.

Students apply the theoretical probability formula \(P(\text{event})=\frac{\text{number of desired outcomes}}{\text{total number of outcomes}}\) and the experimental probability formula \(P(\text{event})=\frac{\text{number of times the event occurred}}{\text{total number of trials}}\). Problems require students to compare predicted probabilities to recorded data, calculate differences, interpret frequency tables, and determine which spinner model most closely matches the experimental results.

By expressing answers as fractions and decimals, students strengthen their fluency in multiple representations of probability. The analysis component encourages reasoning about why experimental results may differ from theoretical expectations, helping students connect probability to long-run relative frequency.
