Law of Total Probability

작성자 Uploader : math1 작성일 Upload Date: 2016-03-20변경일 Update Date: 2016-03-20조회수 View : 345

The probability P(E) of an event E is a real number in the range of 0 to 1. The probability of an impossible event is 0 and that of an event certain to occur is 1.

Total probability can be calculated by follow formula.

P(A + B) = P(A) + P(B) ? P(A, B)

P(A + B) = the probability that either A or B occur alone or that both occur together
P(A) = the probability that A occurs
P(B) = the probability that B occurs
P(A, B) = the probability that both A and B occur simultaneously
