A freelance computer consultant keeps a database of her clients, which contains the names S = (Acme, Brothers, Crafts, Dion, Effigy, Floyd, Global, Hilbert). The following clients owe her money: A = (Acme, Crafts, Effigy, Global}. The following clients have done at least $10,000 worth of business with her: B = {Acme, Brothers, Crafts, Dion}. The following clients have employed her in the last year: C = {Acme, Crafts, Dion, Effigy, Global, Hilbert). A subset of clients is described that the consultant could find using her database. HINT [See Example 4.] The clients who either do not owe her money, have done at least $10,000 worth of business with her, or have employed her in the last year. Write the subset in terms of A, B, and C. OA'UBUC OAUBUC OAUBUC OA'UBUC OA'UBUC List the clients in the subset. O(Acme, Crafts, Effigy, Global} O(Acme, Brothers, Crafts, Dion, Effigy, Floyd, Global, Hilbert) O(Acme, Brothers, Crafts, Dion) O(Acme, Crafts, Dion, Effigy, Global, Hilbert)
