# 7th Grade Math - Theoretical Probability

| No Comments | No TrackBacks

So we know the difference between probability and experimental probability, but what about theoretical probability? Whereas experimental probability is the likelihood that a particular event happens, theoretical probability is the probability of an event when all outcomes are equally likely. In experimental probability, you determine the probability by dividing the number of times the event occurs by the total number of trials. With theoretical probability, you determine the probability by dividing the number of ways the event can occur by the total number of equally likely outcomes.

Confused? Don't be! Just check out today's free 7th grade math video and let Edward Burger teach you all about theoretical probability. In two lectures, he'll give you real world examples so that you have a strong understanding of the concept. Just don't forget to click on the forward button directly to the left of the timestamp to move to the next lecture on the video. And just in case that is not enough, we're publishing the subchapter worksheet for Introduction to Probability. Watch the videos and then test your knowledge with the worksheet. Between the two, you'll get a great overview in probability! ## Twitter Updates
