Experimental and Theoretical 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 conducted.

Front

How do you calculate experimental probability?

Back

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

Front

What is theoretical probability?

Back

Theoretical probability is the likelihood of an event happening based on all possible outcomes.

If a die is rolled, what is the theoretical probability of rolling a 3?

Back

Theoretical probability = 1/6, since there is one favorable outcome (rolling a 3) out of six possible outcomes.
