If a and b are independent find pr a or b
WebIf you can easily find P (A), P (B), and P (A and B) using logic or are provided these values, then we can test for independent events using the multiplication rule for independent events: IF P (A)*P (B) = P (A and B) THEN A and B are independent events, otherwise, they are dependent events. WebIf A and B are independent events, then P (A│B) = P (A) Using the Multiplication rule of probability, P (A ∩ B) = P (B) .P (A│B) P (A ∩ B) = P (B) .P (A) Note: A and B are two events associated with the same random experiment, then A and B are known as independent events if P (A ∩ B) = P (B) .P (A) What are Mutually Exclusive Events?

WebIf \(A\) and \(B\) are independent events then intuitively it seems clear that any event that can be constructed from \(A\) should be independent of any event that can be constructed from \(B\). This is the case, as the next result shows. Moreover, this basic idea is essential for the generalization of independence that we will consider shortly. WebFor independent events A and B, this is equal to P (B)P (A) + P (B)P (Ac) = P (B) (P (A) + P (Ac)) = P (B) (1) = P (B), since the probability of an event and its complement must always sum to 1. Bayes's formula is defined as follows: Example Suppose a …

WebP(A∩B) is the probability of both independent events “A” and "B" happening together, P(A∩B) formula can be written as P(A∩B) = P(A) × P(B), where, P(A∩B) = Probability of … WebNote 1: After reducing to (1), it is not correct to say Pr(Ac \B) = Pr(Ac)Pr(B) and Pr(A\B) = Pr(A)Pr(B), and cancel the Pr(B)’s to reduce to Pr(Ac)+Pr(A) = 1: we don’t know that the events A and B are independent. Note 2: Some people reasoned out the truth intuitively; I docked points for this because the
WebThus, if two events A and B are independent and P ( B) ≠ 0, then P ( A B) = P ( A). To summarize, we can say "independence means we can multiply the probabilities of events to obtain the probability of their intersection", or equivalently, "independence means that conditional probability of one event given another is the same as the ...
