Explain the difference between experimental and theoretical probability.

• Experimental probability is based on theoretical calculations, while theoretical probability is based on actual outcomes.

• Experimental probability is based on actual outcomes from an experiment, while theoretical probability is based on mathematical calculations and predictions.

• Experimental probability is based on guessing, while theoretical probability is based on actual outcomes.

• Theoretical probability is based on guesses, while experimental probability is based on mathematical calculations.
