WebNow, the Law of Total Probabiliyy can be used to calculate P (B)P (B) in the above definition. The law requires that you have a set of disjoint events DiDi that collectively "cover" the event BB. Then, instead of calculating P (B)P (B) directly, you add up the intersection of BB with each of the events EiEi: P (B)=∑P (B∩Ei)P (B)=∑P (B∩ ... WebThe Bayes’ theorem can be generalized to yield the following result. Theorem 2. Law of Total Probability If A1,A2,...,An is a partition of the sample space and B is an event in the event space, then P(B) = Xn i=1 P(B Ai)P(Ai) (6) The law of total probability suggests that for any event B, we can decompose B into a sum of n disjoint subsets Ai ...
