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.

In a Venn diagram, it is common practice to label the intersection section with the number of elements that are shared between the two sets. In your example, the correct way to label the intersection section would be to label it as "5" since that is the number of elements that are shared between the two sets of 10. It is important to label the sections accurately to clearly represent the relationship between the sets.
