SOLUTION: Let S = {1,2,3,...,18,19,20} be the universal set.
Let sets A and B be subsets of S, where:
Set A={2,3,5,6,7,11,12,13,14,16,17,19,20}
Set B={3,6,7,11,13,14,16,17}

Question 1195638: Let S = {1,2,3,...,18,19,20} be the universal set.
Let sets A and B be subsets of S, where:
Set A={2,3,5,6,7,11,12,13,14,16,17,19,20}
Set B={3,6,7,11,13,14,16,17}
LIST the elements in the set
A∪B:A∪B= {____ }
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

The union of two sets contains elements that are in one set, the other set, or both. For example: The Union of A and B contains the element 2 because 2 is an element of A and it contains the element 6 because 6 is an element of both A and B. The element 1 of the universal set is not an element of A union B because neither A nor B contain the element 1. Since all of the elements of B are also in A, the union set is identical to A
The intersection of two sets is the set of elements that are in both of the sets. For example, the element 2 is not in the intersection because 2 is only in set A, and the element 1 is not in the intersection because 1 is not in either A or B. Since all of the elements in B are also in A, the intersection set is identical to set B.
