Question

जर n (A) = 20, n (B) = 28 व n (A ∪ B) = 36 तर n (A ∩ B) = ?

Answer 1

n(A interaction B)=n(A)+n(B)-n ( A union B)

=20+28-36

=48-36

=12

Answer 2

Solution :

It is given that ,

n(A)= 20 , n(B) = 28,

n (A ∪ B) = 36 तर n (A ∩ B) = ?

n(A ∩ B) = n(A)+n(B)- n (A ∪ B)

= 20 + 28 - 36

= 48 - 36

= 12
