Question

The symmetric difference of set A and B, denoted by A∆B, is the set containing elements in either
A or B, but not in both A and B. Answer the followings:

(a) Let A = {a, e, f, y, q, w} and B = {e, z, z, q,p, f}. Find AAB.
(b) Draw Venn Diagram of (AUB) – (AnB) and (A-B)U(B-A). Conclude that AAB = (AUB)- (ANB)
and AAB=(A - B)U(B-A).
(c) Using set identities and part (b) show that AAB = (ANB)n (AUB).
