Very often we know a conditional probability in one direction, say P„E j F”, but we would like to know the conditional probability in the other direction. Bayes’ theorem provides a way to convert from one to the other. We can derive Bayes’ theorem by starting with the definition of conditional probability: P„E j F” = P ...
