Given events X and Y with these probabilities P(X ∪ Y ) = 0.7 = 7/10 P( Y - X) = 0.3 = 3/10 P(Y ∩ X) = 0.2 = 1/5 Calculate, and give your answer as a reduced fraction. P( (Y-X) ∪ (X-Y)) =  P(Xc) =  P(X|Y) = P(Y| Xc) =  Are X and Y mutually exclusive (yes or no)  Are X - Y and Y - X mutually exclusive (yes or no)
