Question 1195636: Let S = {1,2,3,...,18,19,20} be the universal set.
Let sets A and B be subsets of S, where:
Set A={2,3,4,6,9,10,16,17}
Set B={2,3,4,8,9,214,15,16,18,20}
LIST the elements in Set A and Set B: {
}
LIST the elements in Set A or Set B: {
}
Enter the elements as a list, separated by commas. If the result is the empty set, enter DNE

LIST the elements in Set
A and B: { }
Intersection A ∩ B: in both A and B
.
A ∩ B={2, 3, 4, 9, 16}
LIST the elements in Set
A or B: { }
Union A ∪ B: in A or B (or both)
A ∪ B ={2, 3, 4, 6, 8, 9, 10, 15, 16, 17, 18, 20, 214}
