I know the Bayes rule is derived from the conditional probability. But intuitively, what the difference? The equation looks the same to me. The nominator is the joint probability and the denominator is the probability of the given outcome.
This is the conditional probability: P(A∣B)=P(A∩B)/P(B)
This is the Bayes' rule: P(A∣B)=P(B|A)*P(A)/P(B).
Isn't "P(B|A)*P(A)" and "P(A∩B)" the same? When A and B are independent, there is no need to use the Bayes rule, right? What's the difference intuitively between conditional probability and bayes rule?
