If `n(AcapB)=51,n(A)=20,n(B)=44`,find `n(AuuB)`.

If n(A)=20,n(B)=8andn(AuuB)=28 , find n(AcapB) .

If n(U)=50,n(A)=20,n(A uu B)=18 then n(B-A) is

If n(u)=100,n(A)=50,n(B)=20 and n(A nnB)=10, then n{(AuuB)^©}

If n(mu)=100,n(A)=50,n(B)=20 and n(A cap B) =10, then n[(AcupB)]=

If A and B are subsets of the universal set X, where n(X)=50,n(A)=35,n(AcapB)=10 and n[(A cupB)]'=3 , then the value of n(B),n(AcapB),n(AcupB) are respectively.

If n(A )= 20 n(A cap B) = 10,and n(A cup B)=70 then find n(B).

Let A and B be two sets such tat :n(A)=20,n(A uu B)=42 and n(A nn B)=4 Find n(B)
