Let U denote the set of all students in the business college of a certain university. Let A = {x ? U | x had taken a course in accounting} B = {x ? U | x had taken a course in economics} C = {x ? U | x had taken a course in marketing}. Write the set that represents each statement. (a) The set of students who have had courses in accounting but not courses in marketing or economics ? A ? (C? ? B?) ? A ? (C ? B)? ? A ? C? ? B? ? A ? (C? ? B?) ? A ? (C ? B)? (b) The set of students who have had at least one of the three courses ? A ? C ? B ? A ? C ? B ? A ? (C? ? B?)? ? A ? (C ? B) ? A ? (C? ? B?)? (c) The set of students who have had all three courses ? A? ? C? ? B? ? A ? (C? ? B?)? ? (A ? C ? B)? ? A ? (C ? B) ? A ? C ? B
