5 Rules of Probability in One Picture (Cat and Dog Edition)

Knowledge of the basic rules of probability is a must-have for any data scientist. But if you're a visual learner like me, learning the algebraic representations of the 5 basic rules of probability (i.e. P(A) + P(B) = 1) is a challenge. I've never been very good at memorizing formulas, but images stick in my head like ear worms. Whenever I come across a new formula, I try to make it visual with a picture or doodle. The following picture shows some of the images I created to learn the…See More
