Venn diagrams?

  1. Jan 17, 2007 #1
    just a clarification cause it's been so long
    if you have intersection in a venn diagram, is it general practice to label the section including the intersecting diagrams.
    say you have two sets of 10 with 5 things in the intersect. do you label it 10 in the 2 sets and 5 in the intersect. or. 5 in each section?

    It is much more clarifying to split up the 10 in one set in "those 5 that lie in the intersection and those other 5 that does not lie in the intersection"

    thus, the image will be of 3 5's, distributed on three regions.
