Experimental probability is the probability determined by conducting an experiment and observing the outcomes.

Front

What is theoretical probability?

Back

Theoretical probability is the probability calculated based on the possible outcomes in a perfect scenario, without conducting any experiments.

Front

How do you calculate experimental probability?

Back

Experimental probability = (Number of successful outcomes) / (Total number of trials).
