Theoretical and Experimental Probability

Front

What is experimental probability?

Back

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

How do you calculate experimental probability?

Back

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