Labeling Intersection in Venn Diagrams

[Physics is Phun]

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.
