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, 9, 12, 13, 14}
Set B =
{1, 4, 5, 7, 16, 18, 19}
Set C= {4, 6, 8, 9, 11, 13, 15, 16, 17, 19}
LIST the elements in the set (AUBUC)
(AUBUC) = {
-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 BnC)
(An BnC) = {
}
Enter the elements as a list, separated by commas. If the result is the empty set, enter DNE

Answer :

The elements of (A∪B∪C) = {1, 4, 5, 6, 7, 8, 9, 11, 12, 13, 14, 15, 16, 17, 18, 19}

The elements of (A∩B∩C) = DNE

Sets

From the question, we are to list the elements of the given sets

From the given information,

Set A = {7, 9, 12, 13, 14}

Set B = {1, 4, 5, 7, 16, 18, 19}

Set C = {4, 6, 8, 9, 11, 13, 15, 16, 17, 19}

We are to list the elements of (A∪B∪C)

(A∪B∪C) = {1, 4, 5, 6, 7, 8, 9, 11, 12, 13, 14, 15, 16, 17, 18, 19}

Also, we are to list the elements of (A∩B∩C)

(A∩B∩C) = { } OR ∅

Since this is an empty set

(A∩B∩C) = DNE

Hence,

The elements of (A∪B∪C) = {1, 4, 5, 6, 7, 8, 9, 11, 12, 13, 14, 15, 16, 17, 18, 19}

The elements of (A∩B∩C) = DNE
