- 2. 32 students take basketball and volleyball.
- 3. 10 students take soccer and volleyball.
- 4. 14 students take nothing. # Decide on the method you will use.<br /> Venn diagram<br />V= volleyballB= basketballS= soccer # Set out your calculation carefully.<br />228600102870 <br />V14B<br />32<br />10<br /> 24 S<br />Answer is 70.<br /> # Make sure your answer is reasonable.<br /> The answer is not 80 (14+24+10+32) is because there are 32 students take basketball and volleyball, and 10 students take soccer and volleyball. So we should use 32-10.<br />
