Let S be the universal set, where: S = {1, 2, 3, ..., 18, 19, 20} Let sets A and B be subsets of S, where: Set A = {1, 4, 5, 10, 12, 14, 20} Set B = {1, 2, 11, 12, 16, 17, 18, 19} Find the following: LIST the elements in the set (A U B): (AUB) ={ Enter the elements as a list, separated by commas. If the result is the empty set, enter DNE LIST the elements in the set (An B): (AnB) = { Enter the elements as a list, separated by commas. If the result is the empty set, enter DNE Hint: You may want to draw a Venn Diagram to help answer this
