WebMar 9, 2024 · Joint Probability is a type of probability that deals with the intersection of two independent events. It can be applied to situations where more than one independent observation can occur at the same time or in situations where we want to know the possibility of two independent events occurring separately.

Notice how the data quickly overwhelms the prior, and how the posterior becomes narrower.
