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.

Front

How do you calculate Experimental Probability?

Back

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

Front

How do you calculate Theoretical Probability?

Back

Theoretical Probability = (Number of favorable outcomes) / (Total number of possible outcomes)

What is the difference between Experimental and Theoretical Probability?

Back

Theoretical Probability is what is expected to happen while Experimental Probability is what actually does happen.
