1. Let U, A, and B be sets such that AC U and BCU, where U is the relative universal set. The symmetric difference between A and B is the set of elements that are either in A or in B but not in both, and it is denoted by . (a) Write AAB in terms of A, B, A, B and their unions and inter- sections. (b) Draw the Venn Diagrams representing the following two sets: i. AAB ii. AAB
