Theoretical probability is based on mathematical calculations or predictions, while experimental probability is based on actual observations or experiments.

Study Notes

Probability

Theoretical Probability: The probability of an event occurring based on the number of favorable outcomes divided by the total number of possible outcomes, assuming all outcomes are equally likely.

Experimental Probability

Experimental Probability: The probability of an event occurring based on the results of repeated trials or experiments, calculated by dividing the number of times the event occurs by the total number of trials.

Comparing Theoretical and Experimental Probability

Key difference: Theoretical probability is based on theoretical calculations, while experimental probability is based on actual experimental data.
Theoretical probability assumes all outcomes are equally likely, while experimental probability is influenced by the actual results of trials.

Test your knowledge of theoretical and experimental probability with this quiz designed for grade 7 students following the Ontario curriculum expectations. This quiz will assess your understanding of concepts such as sample space, outcome, event, and calculating probabilities. Challenge yourself and see how well you can apply these concepts to real-life situations!
