    Question [SOLVED] venn diagram help!

    Heyhey, can someone please help me with this question?

    The universal set, U and the two sets A and B cantained within are such that:
    -n(AnB)=6
    -n(A)= 27
    -n(B)=46
    -n(U)=70

    determine 1) n(AuB) 2) n((AuB)')


    I have so far found out that A,B and AnB don't add up to 70, how do you work out the actual number of A and B?

    thank you xxx
