If A and B are two sets such that `n(A)=7, n(B)=6and (A nnB)ne phi` Then the greatest possible value of n `(A Delta B)` is

If A and B are two sets such that n(A)7, n(B),=6 and n(AnnB) ne phi The least possible value of n(A Delta B), is

If A and B are two sets such that n(A)7, n(B),=6 and n(AnnB) ne phi The least possible value of n(A Delta B), is

A and B two sets such that n(A)=3 and n(B)=6 , then

A and B two sets such that n(A)=3 and n(B)=6 , then

A and B are two sets such that n(A) = 12, n(B) = 10, A nn B ne phi and B cancelsub A . The least possible value of n(A Delta B) is "_____" .

If A and B are two sets such that n(A)=20,n(B)=24 and n(A uu B)=40 then write n(A nn B)

If A and B are two sets such that n(A)=115,n(B)=326,n(A-B)=47 then write n(A uu B)

If A and B are two sets, then n(A)+ n(B) is equal to

If A and B are two sets such that n(A) =23, n(B)=37 and n(A - B) =8 then find n(Acup B) .
