If A = {1, 3, 5, 7, 9} and B = {2, 3, 5, 7}, what is A ∪ B?

• {3, 5, 7}
• {2, 3, 5, 7}
• {2, 3, 5, 7, 9}
• {1, 2, 3, 5, 7, 9}

If A = {1, 3, 5, 7, 9} and B = {2, 3, 5, 7}, what is A ∩ B?

• {3, 5, 7}

• {2, 3, 5, 7}

• {2, 3, 5, 7, 9}

• {1, 2, 3, 5, 7, 9}

The Universal Set = { -4, 3, -2, -1, 0, 1, 2, 3 ,4} and A = {0}.
What is the complement of A?

• {-4, -3, -2, -1, 0, 1, 2, 3}
• {-3, -2, -1, 1, 2, 3}
• {-4, -3, -2, -1, 1, 2, 3, 4}
• {-4, -3, -2, -1, 1, 2, 3}

If
P = {0, 1, 2, 3, 4}, Q = {4, 6, 8}
R = {6, 12, 18} Then what is (P ∩ Q) ∪ (Q ∩ R)?

• {4}
• {4, 6}
• {4, 6, 8}
• {1, 2, 3, 4, 6, 8}

If
P = {0, 1, 2, 3, 4}, Q = {4, 5, 6, 7}
R = {3, 6, 9}, and S = {6, 12, 18}
Then what is (P ∪ Q) ∩ (S ∪ R)?

• {6}
• {3, 6}
• {4, 6}
• {1, 2, 3, 4, 5, 6, 7, 9, 12, 18}

If
A = {1, 3, 5, 15},
B = {2, 3, 5, 7}
C = {2, 4, 6, 8}
then what is (A U B) ∩ C ?
 

• {1,3,5}
• {1,2,3}
• {2,3,5}
• {2}

If 
U (the universal set) = {1, 3, 5, 7, 9, 11, 13, 15, 17} and W = {5, 7, 9, 11}, then W' = . .  ..
 

• 1, 3, 13, 15, 17}
• {1, 3}
• {2, 4, 6, 8, 10, 12, 14, 16}
• {1, 3, 5, 7, 9, 11, 13, 15, 17}{

From the above Venn diagram, what is the set S ∩ T?

• {casey, drew, jade, glen}
• {alex, casey, drew,hunter}
• {casey, drew}
• {drew, jade}

From the above Venn diagram, what is the set (S ∪  T) ∩ V?

• {casey, drew, jade, glen}
• {alex, glen, hunter, jade}
• {casey, drew, glen}
• {drew, jade}

From the above Venn diagram, what is the set S' ? Look at ALL of the Universal set called "U."

• {casey, drew}
• {blair, erin, francis, glen, jade, ira}
• {blair, erin, francis, ira}
• {jade, glen, blair, erin, francis, ira}
