I. Bayes Theorem : In probability & Statistics, Bayes theorem describes the probability of event, based on prior knowledge of conditions related to event.In simple terms, Bayes’ Theorem helps us adjust the probabilities when we receive new data. It provides a systematic way to reason and update our situation. Formula : P(A|B) = P(B/A)P(A) / P...
