Sample Problems For Intersection and Union

Write answers in ascending order, separated by commas. Example: A = {-3, 1, 2, 5 }.

1. N = {4, 7, 8, 10} O = {1, 4, 5, 7, 10}

N ∪ O = {}
N ∩ O = {}

2. L = {0, 2, 4, 8, 10} M = {}

L ∪ M = {}
L ∩ M = {}

Write answers in ascending order, separated by commas. Example: A = {-3, 1, 2, 5 }.

1. Y = {-3, 7, 8} Z = {-3, -2, -1, 0, 5}

Y ∩ Z = {}
Y ∪ Z = {}

2. W = {1, 4, 5, 7, 8, 9} X = {1, 4, 5, 10}

W ∩ X = {}
W ∪ X = {}

Write answers in ascending order, separated by commas. Example: A = {-3, 1, 2, 5 }.

1. D = {-4, 1, 2, 9} E is the set of negative odd numbers.

D ∩ E = {}

2. S = {-5, -4, 5, 7, 8, 9} T is the set of negative odd numbers.

S ∩ T = {}

#	Problem	Correct Answer	Your Answer
1	N = {4, 7, 8, 10} O = {1, 4, 5, 7, 10}	N ∪ O = {} N ∩ O = {}
Solution N ∪ O = the set of all members set N and all members of set O N ∩ O = the set of members that are common in both sets N and O

2	L = {0, 2, 4, 8, 10} M = {}	L ∪ M = {} L ∩ M = {}
Solution L ∪ M = the set of all members set L and all members of set M L ∩ M = the set of members that are common in both sets L and M Since M is an empty set, L and M have no common members.

#	Problem	Correct Answer	Your Answer
1	D = {-4, 1, 2, 9} E is the set of negative odd numbers.	D ∩ E = {}
Solution D ∩ E = the set of members that are common in both sets D and E Since E includes all negative odd numbers, D ∩ E is the set of negative odd numbers in D.

2	S = {-5, -4, 5, 7, 8, 9} T is the set of negative odd numbers.	S ∩ T = {}
Solution S ∩ T = the set of members that are common in both sets S and T Since T includes all negative odd numbers, S ∩ T is the set of negative odd numbers in S.
