What is the Venn diagram?
It is defined as the diagram that shows a logical relation between sets.
The Venn diagram consists of circles to show the logical relation.
From the Venn diagram:
Total number of students who enrolled in chemistry only = 9
Total number of students who enrolled in biology only = 11
Total number of students who enrolled in physics only = 7
Total number of students who enrolled in biology and chemistry but not in physics = 5
Total number of students who enrolled in biology and physics but not in chemistry = 4
Total number of students who enrolled in chemistry and physics but not in biology = 6
Total number of students who enrolled in all three subjects = 3
Total number of students who did not enroll in anyone = 18
Total number of students = 63
Thus, the number of students in the 2015 senior class is 63, the number of students taking chemistry and biology, but not physics is 5, and the number of students not taking science is 18.
