P(A) - 3 . P(B ) = 3 . and PLA. Suppose A and B are events such that P(A) = -, P(B) = -, and P(A or B) = -. Complete parts (a) and (b) below. a. Are events A and B mutually exclusive? Explain your answer. A. No; P(A) is not equal to P(B). B. Yes; P(A) + P(B) is equal to P(A or B). C. Yes; P(A or B) is greater than P(A). D. No; P(A) + P(B) is not equal to P(A or B). b. Determine P(A & B). P(A & B) = (Type an integer or a simplified fraction.)
