Question

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, 11, 13, 15, 16, 19, 20}Set B = {1, 2, 3, 4, 5, 6, 10, 11, 14, 16, 17, 18, 19}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 DNEYou may want to draw a Venn Diagram to help answer this question.

Answer 1

Answer:

a) Set (A and B) = {2, 3, 4, 6, 11, 16, 19}

b) Set (A or B) = {1, 2, 3, 4, 5, 6, 10, 11, 13, 14, 15, 16, 17, 18, 19, 20}

Step-by-step explanation:

Given:

S = {1,2,3, ... ,18,19,20) be the universal set

Set A = {2, 3, 4, 6, 11, 13, 15, 16, 19, 20}

Set B = {1, 2, 3, 4, 5, 6, 10, 11, 14, 16, 17, 18, 19}

To find:

a) the elements in Set A and Set B

b) the elements in set A or set B

a) Elements in set A and set B will include the numbers common to both sets

Set (A and B) = {2, 3, 4, 6, 11, 16, 19}

b) Elements in set A or set B will include the union of elements in set A and elements in set and any repetition will be written once

Set (A or B) = {1, 2, 3, 4, 5, 6, 10, 11, 13, 14, 15, 16, 17, 18, 19, 20}
