In a class of 40 pupils,30 students study biology,22 study physics and 21 study chemistry,2 study physics only,3 study study chemistry only and 7 study biology only.
Represent the information on a Venn diagram
Let's represent the information on a Venn diagram:
1. Draw a circle to represent Biology students (30 total).
2. Draw a circle to represent Physics students (22 total).
3. Draw a circle to represent Chemistry students (21 total).
4. Place the number of students who study both Biology and Physics in the overlapping section between Biology and Physics.
5. Place the number of students who study both Physics and Chemistry in the overlapping section between Physics and Chemistry.
6. Place the number of students who study both Biology and Chemistry in the overlapping section between Biology and Chemistry.
7. Place the number of students who study all three subjects in the center where all three circles overlap.
Label the numbers of students who study Biology only, Physics only, and Chemistry only on the respective sections of the Venn diagram.
