Answer 7

The complement of a set will be all of the elements that are not included in the original set. Using your question: since A={2,3}, the complement of A will be all of the numbers in the universal set that are not in A. Thus, A'={1,4,5}.

Answer 8

False. A set is a subset of another set only if all of the elements in the first set are also elements in the second set. As all of the elements in B are not in A, then B is not a subset of A.

Answer 9

Like with the first one that you posted, the complement of a set is all of the elements that are not included in the original set. Now, since P={2,4,6,8}, what are the elements in the universal set, U, that are not in P (and thus P')?
