Answer 1

Answer:

Step-by-step explanation:Let C, T, B denote the set of students who play cricket, tennis and badminton respectively

Then we have, n(U) = n(C ∪ T ∪ B) = 84,

n(C) = 28, n(T) = 40, n(B) = 48,

n(C ∩ B) = 6, n(T ∩ B) = 4, n(C ∩ T ∩ B) = 0

Now, n(C ∪ F ∪ V) = n(C) + n(T) + n(B) - n(C ∩ B) - n(T ∩ B) - n(C ∩ T) + n(C ∩ T ∩ B)

⇒ 84 = 28 + 40 + 48 - 6 - 4 -  n(C ∩ T)

⇒ n(C ∩ T)  = 116 - 10 - 84

⇒ n(C ∩ T) = 22

Hence, No. of Students who plays cricket but tennis = n(C) - n(C ∩ T)

                                                                                          = 28 - 22

                                                                                          = 6
