    Draw a Venn diagram such that B is a proper subset of A, i.e. the whole of B is within A, but B does not equal A.

    Now given B={10,12,14,16,18}, complete the elements of A = {all even integers from 2 to 20 inclusively}.

    Start with 2, which has to be written witin A, but outside of B. Continue this way. If the element is already in B, proceed to the next one.

    B' would consist of the elements in A but not in B.
