Two events A and B are said to be independent if:
A) P(A and B)= P(A)· P(B).
B) P(A and B)= P(A)+ P(B).
C) P(A/B)= P(B).
D) P(B/A)= P(A).
E) P(A or B)= P(A)· P(B).

Quizplus · Accepted Answer

The formula P(A and B)= P(A)·P(B) is the definition of independence between two events. It means that the probability of both events occurring together is equal to the product of their individual probabilities.
