In a class of 60 students, 25 students play cricket and 20 students play tennis, and 10 students play both the games. Find the number of students who play neither?
Let C be the set of students who play cricket and T the set of students who play tennis.
Total number of students = 60 ⇒n(U)=60
Number of students who play cricket = 25 n(C)=25
Number of students who play tennis = 20 n(T)=20
Number of students who play both the games = 10
Number of students who play any one game
Number of students who play neither
