Complete the following problems, Please show all your work and make sure you have answered all the parts of each question. You may find it helpful to illustrate a problem with an example, but remember that examples are not proof. Unless otherwise stated, the sets are general sets. Note that A\B=A-B and D = D 2) Prove (A-B) U (B-A) = (A UB) - (An B) 3) Prove Ax(BIC) = (AxB) \(AXC) 4) (a) Prove A-(B-C) = (A-B) u (An C) but (A-B)-C = A-(BUC) (b) Prove (A-B)-C = A - (BC) (c) Prove that set difference is NOT associative, by providing an explicit example, i.e. find concrete sets A, B, and C, such that A-(B-C) and (A-B)-C are not the same.
