Answer 2

Solution for the Number of Students Playing Football, Volleyball, and Basketball Simultaneously

To find the number of students playing football, volleyball, and basketball simultaneously, we can use the principle of inclusion-exclusion.

1. First, we add the number of students playing each sport: 24 (football) + 18 (volleyball) + 12 (basketball) = 54. 2. Then, we subtract the number of students playing two sports simultaneously: 10 (football and volleyball) + 8 (football and basketball) + 5 (volleyball and basketball) = 23. 3. After this, we subtract the total from the number of students in the class: 35 - 23 = 12.

So, 12 students play football, volleyball, and basketball simultaneously.

Additional Information

It's important to note that the given information allows us to calculate the number of students playing each combination of sports. For example: - 10 students play football and volleyball only. - 8 students play football and basketball only. - 5 students play volleyball and basketball only.

This information can be used to derive various other combinations of sports played by the students in the class.
