Question

The universal set U is the set of all positive even numbers less than 40.

K is the set of the multiples of 4 less than 40.



What is the complement of set K? is it 2,6,10,14 . . . , 38

Answer 1

Yes. The complement of K (relative to U) is the even numbers less than 40 that are not multiples of 4, i.e.
U \ K = {2, 6, 10, 14, 18, 22, 26, 30, 34, 38}.
