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 = {7, 8, 9, 10, 11, 13, 14, 15, 18, 20}
Set B = {2, 3, 4, 6, 9, 10, 11, 12, 14, 16, 17, 18, 19}
Find the following:
LIST the elements in the set (A ∪ B):
(A ∪ B) = {
Enter the elements as a list, separated by commas. If the result is the empty set, enter DNE
LIST the elements in the set (A ∩ B):
(A ∩ B) = {
Enter the elements as a list, separated by commas. If the result is the empty set, enter DNE
