Final answer:
Out of 30 students, 10 play sports (1/3 of 30), and of those, 4 play soccer (2/5 of 10), so 4 students play soccer.
Step-by-step explanation:
To find out how many students play soccer, we need to follow a two-step calculation based on the information given:
- First, determine how many students play sports. Since 1/3 of the 30 students play sports, we multiply 30 by 1/3:
- 30 students × (1/3) = 10 students play sports.
- Next, figure out how many of these students playing sports also play soccer. Given that 2/5 of those who play sports play soccer, we multiply the 10 students who play sports by 2/5:
- 10 students × (2/5) = 4 students play soccer.
Therefore, 4 students from the class of 30 play soccer.
