Answer» CORRECT answer is (a) P(A|B) = \(\frac{P(B│A)P(A)}{P(B)}\) For explanation: Bayes theorem FORMULA is P(A|B) = \(\frac{P(B│A)P(A)}{P(B)}\) The formula provides relationship between P(A|B) and P(B|A). It is mainly derived from conditional PROBABILITY formula P(A|B) and P(B|A). Where, P(A|B) = \(\frac{P(A∩B)}{P(B)}\). P(B|A) = \(\frac{P(B∩A)}{P(A)}\). |
