What is experimental probability?

Back

Experimental probability is what actually happens based on the outcomes of an experiment.

Front

How do you calculate experimental probability?

Back

Experimental probability is calculated by dividing the number of successful outcomes by the total number of trials.

What is the difference between experimental and theoretical probability?

Back

Experimental probability is based on actual experiments, while theoretical probability is based on expected outcomes.

Back

It means the event is certain to happen.
