What is Experimental Probability?

Back

Experimental Probability is what actually happens based on the results of an experiment.

What is the formula for calculating Experimental Probability?

Back

Experimental Probability = (Number of times an event occurs) / (Total number of trials).

Front

What is the difference between Theoretical and Experimental Probability?

Back

Theoretical Probability is based on expected outcomes, while Experimental Probability is based on actual outcomes from experiments.
