S and T are binary relations on the set {a, b, c, d} and are defined as follows: S%3{ (а, b), (a, с), (b, d), (d, c)} T3{ (b, b), (с, а), (с, d), (а, d)}

Let U={1,2,3,6,8,9,10,12,13}, X= {2,6,9,12}, Y = {2,3,6,8,9), and Z={1,2,3,12,13}. List the members of the given set, using set braces. (XNY')U(Z'NY') (XNY')u(Z'NY') = {} (Use a comma to separate answers as needed.)

The difference of two sets, A – B, is defined as the set containing all elements of A except those in B. That is, A - B = AN B'. Find A - B for the pair of sets if U = {1, 2, 3, 4, 5, 6, 7, 8, 9}. (Enter your answer in roster notation. Enter EMPTY or Ø for the empty set.) A = {3, 5, 9} and B = {2, 4, 6, 7, 8, 9} A - B =
