解析 C If two events are independent, their probability of their joint occurrence is computed as follows : P(A∩B) =P(A) × P(B). Since we are not given any information on the respective probabilities of A or B, there is not enough information....
Let A and B be events, with A' and B' being their negations. Given: P(AB) = P(A' B), and P(A B') = P(A' B'). Prove that A and B are independent. Assume events A and B are independent and Pr(A)=0.3 and ...
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....

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...
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 equivalent statement is ...
