Suppose U = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 } is the universal set and Q = { 3, 6, 9 }. What is Q?

A- { 3, 6, 9 }
B- { 4, 5, 7, 8 }
C- { 1, 2, 4, 5, 7, 8, 10 }
D- { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 }

--------------------------------------------------------------------------------------------------

For questions 4 and 5, suppose U = { 1, 2, 3, 4, 5, 6, 7, 8 }, A = { 1, 3, 5, 7 }, and B = { 4, 5, 6 }. Tell whether each statement is true or false.

4. A ⊆ B

5. B ⊆ U
