(a) If A and B are mutually exclusive events, compute P(A or B). (b) If P(A and B) = 0.1, compute P(A or B). 4 Basic Computation: Addition Rule Given P(A) = 0.7 and P(B) = 0.4: (a) Can events A and B be mutually exclusive? Explain. (b) If P(A and B) = 0.2, compute P(A or B). 5. | Basic Computation: Multiplication Rule Given P(A) = 0.2 and P(B) = (a) If A and B are independent events, compute P(A and B)
