Let U = {all integers}.

Consider the following sets:

A = {x | x ∈ U and x > 3}

B = {x | x ∈ U and x is an even integer}

C = {x | x ∈ U and 2x is an odd integer}

D = {x | x ∈ U and x is an odd integer}

Use the defined sets to answer the questions.

Assuming 0 is an even integer, which set is the complement to set B?

Which set is an empty set?

Which set would contain the subset E = {1, 3, 5, 7}?
