    You need to show a Venn Diagram for this question

    Have you done Venn diagrams before?

    Draw two intersecting circles, call then F and R
    put 8 in the intersection of F and R.
    put 17-8 or 9 in the region of F not intersected.
    put 23-8 or 15 in the region of R not intersected.

    So counting up what we have:
    9 + 8 + 15 = 32 , good!

    How many are "only" in the F circle ?
