How does experimental probability differ from theoretical probability?

• Experimental probability is based on actual experiments, while theoretical probability is based on the possible outcomes.

• There is no difference; they are the same.

• Theoretical probability is always more accurate.

• Experimental probability can only be used in scientific experiments.
