7S: Ch. 7 Topic 2 Theoretical vs. 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.

Front

What is theoretical probability?

Back

Theoretical probability is the ratio of the number of favorable outcomes to the total number of possible outcomes in a given situation.

Front

How do you calculate experimental probability?

Back

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