If n(A) =5, `n(A cup B) = 9`, `n(A cap B)=2`, find n(B).

Choose the coorect altertnative answer for each of the following question: n(B) = 40, n(A cap B) = 20, n(A cup B) = 35 , find n(A).

If n(A) = 15, n(AuuB) = 29, n(A nn B) = 7, then find n(B).

If n(A) = 20, n(A uu B) = 36, n(B) = 28 then find n(A nn B) .

If n(A) = 35, n (B) = n(B) = 40 and n(A cup B) = 50, find n(A cap B) .

If n(A)= 7, n(B)= 13, n(A cap B) = 4 , then n(A cup B) = ?

If n(A) = 5, n(B) = 6 and n(A uu B) = 11, then find n(A nn B).

If A & B are subsets of universal set X and n(x) = 50 , n(A) = 35 , n(A' nn B') = 5 find n(A uu B)
