Calculate P (A or B) in the following scenarios: a. P(A)=0.27, P(B) = 0.03; A and B are mutually exclusive P(A or B) =
P(A or B) = P(A) + P(B)
Since A and B are mutually exclusive, P(A or B) = P(A) + P(B) = 0.27 + 0.03 = 0.30
Since A and B are mutually exclusive, P(A or B) = P(A) + P(B) = 0.27 + 0.03 = 0.30
