Quiz 1. January 19, 2011 Seat # _________ Name: ___ < KEY > ___ Closed book and notes. No calculators. Set theory. For all questions below, consider the universe U = {1, 2, 3, 4, 5, 6}. Let E = {2, 4, 6}, the set of even integers. Let L = {4, 5, 6}, the set of large integers. Let N = {1, 4, 6}, the set of non-prime numbers. Recall that denotes the empty set, denotes union, denotes intersection, and denotes complement. 1. (one point) T F E ′ = {1, 3, 4}. 2. (one point) T F U ′ = . 3. (one point) T F L U = L . 4. (one point) T F ( L N ) ′ = L N . 5. (one point) T F E E ′ = U . 6. (one point) Sketch a Venn diagram showing U , E , and E . ____________________________________________________________ Many correct solutions. Maybe sketch a rectangle and label it U . Maybe partition the area U into six sets labeled one through six. Shade the sets two, four, and six and mark the shaded set as E and the rest as E . Or simply partition U into E and E
