Joint probability, conditional probability, and marginal probability… These are three central terms when learning about probability, and they show up in Bayesian statistics as well. However… I never really could remember what they were, especially since we were usually taught them using formulas, rather than pictures.
Well, for those who learn a bit better using pictures… if you know what a probability distribution is, then hopefully these help with remembering what these terms mean. (Clicking on the image will bring you to the original, hosted on GitHub.)
