A class has 40 students. 20 play cricket, 25 play hockey, and 7 play neither game. How many students play both games?
- 12
- 10
- 8
- None of these
Explanation
Total students = 40
Neither = 7
Students playing at least one game = 40 - 7 = 33
Formula:
n(C or H) = n(C) + n(H) - n(both)
33 = 20 + 25 - Both
33 = 45 - Both
Both = 45 - 33 = 12
