What is experimental probability?

Back

Experimental probability is the probability determined by performing experiments and observing the outcomes.

Front

How do you calculate theoretical probability?

Back

Theoretical probability is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

What is the difference between theoretical and experimental probability?

Back

Theoretical probability is based on expected outcomes, while experimental probability is based on actual trials.
