Twoevents,AandBa...Two events, A and B are independent if the probability of A and B, that is, the probability of their intersection,P(A B) = P(A) P(B). This is automatic but uninteresting if P(A) = 0 or 1, likewise for B. If 0 < P(A), P(B) <1, then an ...
I)If events A and B are independent,then events ¯A and B are independent,and events ¯A and ¯B are also independent .Proof.By definition,A and B independent ⇔P (A ∩B )=P (A )P (B ).But B =(A ∩B )+ ¯A ∪B ,so P (B )=P (A ∩B )+P ¯A ∪B...
Two events A and B will be independent, if (A) A and B are mutually exclusive (B) (C) P(A) = P(B) (D) P(A) + P(B) = 1 View Solution Q2 Assertion :If P(A/B)=P(B/A). A, B are two non mutually exclusive events then P(A)=P(B). Reason: For non mutually exc...
Events A and B are independent; P(A and B ) = 0.15 . What is the probability of event B if P(A) = 0.3?Probability in Math:In the parlance of mathematics, the probability for a given event may be determined in the form of independent probability if i...

Two events A and B are independent if the knowledge that one occurred does not affect the chance the other occurs. For example, the outcomes of two roles of a fair die are independent events. The outcome of the first roll does not change the probability for the outcome of the second ...

解析 C Note that events being independent means that they have no influence on each other. It does not necessarily mean that they are mutually exclusive. Accordingly, P(X or Y)=P(X)+P(Y)-P(X and Y). By the definition of independent events, P(X|Y)=P(X)....
