Question

P(A and B)=P(A)•P(B) is used when two events are used when two events are

Answer 1

Independent.

Explanation:

Independent events:

Two events, A and B, are said to be independent if the probability of both happening is the same as the multiplication of the probabilities of each happening, that is:

`P(A \cap B) = P(A)P(B)`

Thus, P(A and B)=P(A)•P(B) is used when two events are independent.
