Question

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

Answer 1

Answer:

Independent.

Step-by-step 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.
