Question

In a group of 7 students, 3 play volleyball,
4 play badminton, and 2 play neither sport.
Consider the set V represents volleyball player,
and the set B represent badminton player.
(i) How many play both the games?
(ii) Hence find the number of students who
play only Volleyball.
(iii) Calculate n(B-V), n(V'), n(
VB)'
(iv) Show that n(B-V)= n(B) - n(
BV)
[Hint: As proved in questions above, we can say
that n(VUB) = n(V) + n(B) - n(VB)]​
