Suppose X and Y are subsets of some universal set. De Morgan's laws provide expressions for the complement of the union XUY and the complement of the intersection XY. What about the complement of the set difference X\Y? You can answer this question by observing that X\ Y = Yen X. Which of the following expressions is equal to (X\Y) Yen X ΧΟΥ XUY YUX Xº Ye
