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={1,3,4,5,6,8,9,11,14,15,20}
Set B={1,2,5,6,8,9,11,13,14,15,16,18}
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
