In this video, we'll learn how to find the probability of a complement of an event. We first take a concrete example and get an intuition of how probabilities add up to 1. We then prove the formula visually before doing it again using axioms. We finally solve a few practice problems to get a better grasp of this topic. Courses on Khan Academy are always 100% free.
