Question 1157962
This seems to be about logic and Venn diagrams. It also lacks a question.
It was under probability, and getting no attention. The closest place I found to place it was "Logic: Subset".
{{{drawing(300,300,-5,5,-5,5,
rectangle(-4.8,-4.8,4.8,4.8),
circle(1.5,-1.5,3.2),circle(-1.2,1.2,2.6)
)}}} The rectangle represents all adults.
The large circle represents all obese adults.
The smaller circle represents all adults who suffer from diabetes.
The overlap between the two circles represents all adult who are obese and suffer from diabetes.
The sizes of the circles are chosen for better visualization not intended to represent the size of each group.
Let us add the percentage of all adults represented by each figure, based on the data
{{{drawing(300,300,-5,5,-5,5,
rectangle(-4.8,-4.8,4.8,4.8),
circle(1.5,-1.5,3.2),circle(-1.2,1.2,2.6),
locate(-0.8,0.8,obese),locate(-1.2,0.3,diabetic),locate(-0.3,-0.2,"2%"),
locate(1.2,0,obese),locate(0.7,-0.5,not),
locate(1.6,-0.5,diabetic),locate(1,-1,"32%-2=30%"),
locate(-2.9,2.5,diabetic),locate(-2.9,2,not),
locate(-2,2,obese),locate(-2.5,1.5,"4%-2=2%"),
locate(-4.3,4.5,healthy),locate(-4.5,4,not),
locate(-3.6,4,obese),locate(-1.1,4.5,"100%-2%-2%-30%=66%")
)}}} 
The sizes of the circles are not made to represent the percentages,
I needed the text to fit in, too.
