    Thank you
    A and B are subjects of the universal set of U
    #(U)=60
    #(A)=23
    #(B)=35
    #(AUB)=51
    Find #(A/B)'

    Draw a Venn Diagram to illustrate this information
    #(A)=15, #(B)=14 and #(A INTERSECT B)'=7

    long time since I did this and i was browsing as my daughter is doing the Junior Cert this year. With help of my wife here is the first part:
    A on its own = 16
    B on its own = 28
    (A intersect B) = 7

    So A / or less B = 16

    Universe = 60 so #(A/B)' = 60-16 = 44
