About 40 years ago I was reading a business mathematics book and ran across a section that, as I recall, started out with a basic probabilities equation and derived the basic Bayesian equation in one step.
Am I remembering this right? If so could someone post it?
- hgoury 6y agoBy definition: p(A|B) = p(A,B) / p(B) (1) With the same definition, switching A and B roles, we have p(A, B) = p(B|A) p(A) (2) Plug (2) into (1) and you have Bayes rule.
