Distinguish between dependent and independent events.A is correct. Two events, A and B, are independent if and only if P(A│B) = P(A) or, equivalently, P(B│A) = P(B). The wording of the question precludes P(A) = P(B); therefore, responses B and C cannot be correct....
(Caution:3events might be independent in pairs but not independent),Show that 1:Any one event is independent of the intersection of the other two.Proof.If events A j ,j =1,2,3are independent,by condition 2)in the definition above P (A 1∩A 2∩A 3)=P (A 1)P (A 2)P (A ...

For two events A and B , P(A) = 0.8 and P(B) = 0.2. (a) If A and B are independent, then: P(A cup B) = P(A cap B) = P(A|B) = (b) If A and B are dependent and P(A|B) = 0.2 , then: P(A cap ...

on two successive tosses of the same coin. Disjoint events would be the events “heads on the first toss” and “tails on the first toss.” 2 Any set of events is said to be independent if the probability of the intersection of any (finite) number of them is the product of their res...
If event A and event B cannot occur simultaneously, then events A and B are said to be:() A. collectively exhaustive. B. statistically independent. C. mutually exclusive. 相关知识点: 试题来源: 解析 C If two events cannot occur together, the events are mutually exclusive. A good example...
If two events(both with probability greater than)are mutually exclusive, then: a.They also must be independent. b.They also could be independent. c.They cannot be independentIf two events(both with probability greater than0)are mut...
