Experimental Probability

What is experimental probability?

Back

Experimental probability is the ratio of the number of times an event occurs to the total number of trials conducted.

How do you calculate experimental probability?

Back

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

What is the difference between theoretical probability and experimental probability?

Back

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