Let U = {1, 2, 3, 4, 5, 6, 7} (the universal set)  Let A = {3, 5, 7} Let B = {4, 5, 6, 7} a) Find A’ b) Find A ∩ B c) Find A ∪ B d) Find (A’ ∩ B)’

3) Find the intersection of three sets AnBnC, given A= {43, 44, 45, 46), B= {40, 42, 44, 46, 48) and C= {46, 47, 48, 49}. 5) Find the union AUBUC and the intersection AnBnC of three sets, given A= {2, 8, 10), B= {3, 6, 8, 12} and C= {8, 14, 20).

A = {3,5,7,9,11} B={7,9,11,13}  C={11,13,15} and D={15,17} find A ∩ B A U B (A ∩ B) U (C ∩ D)

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 {12, 18, 20} Set B = {3, 7, 13, 18, 20} Find the following: LIST the elements in the set (AU B): (AUB) = { } 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 n B): (AN B) = { } %3D Enter the elements as a list, separated by commas. If the result is the empty set, enter DNE You may want to draw a Venn Diagram to help answer this question.
