We know the total number of students is equal to the number of people in physics and biology P B Pcup B P B plus the number of people in neither of the sets. So 6 people are left over to go in the section that is blank.

Despite Venn diagram with 2 or 3 circles are the most common type there are also many diagrams with a larger number of circles 567810. When we do this the answer is 70.
