Events A and B are mutually exclusive. Which of the following statements is also true?

-A and B are also independent.

-P(A ∪ B) = P(A)P(B)

-P(A ∪ B) = P(A) + P(B)

-P(A ∩ B) = P(A) + P(B)

If A and B are independent events, then

-P(A) must be equal to P(B)

-P(A) must be greater than P(B)

-P(A) must be less than P(B)

-P(A) must be equal to P(A¦B)
