Experimental & Theoretical Probability

Front

What is Experimental Probability?

Back

Experimental Probability is the probability based on the results of an experiment or trial. It is calculated by dividing the number of times an event occurs by the total number of trials.

What is Theoretical Probability?

Back

Theoretical Probability is the probability based on the possible outcomes in a perfect world. It is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

How do you calculate Experimental Probability?

Back

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