If A and B are two sets such that `n(AuuB)=50`,n(A)=28,n(B)=32,then find `n(AnnB)`.

If n(A)=110,n(B)=300,n(A-B)=50,then find n(AUB).

If A,B are two sets and U is the universal set such that n(U)=700,n(A)=200,n(B)=300 and n(AnnB)=100 .Find n(A'nnB') .

If A and B are two finite sets,then prove that n(A uu B)=n(A)+n(B)-n(AnnB)

If n(A)=80,n(B)=30,n(AuuB)=100 ,then find n[(A-B)uu(B-A)] .

If n(A)=75,n(B)=45, n(AuuB) =90,then find n[(A-B)uu(B-A)]

Establish that: n(A uu B)=n(A)+n(B)-n(AnnB)

If n(A-B)=10,n(AnnB)=5 and n(B-A)=20 ,then find n(B) and n(AuuB) .

For any two sets A and B prove that A nn (AuuB)=A

For any two sets A and B prove that n(A-B)=n(A)-n(AnnB) .

Is n(A-B)=n(A)-n(B)?
