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

If n (A-B)=10, n(B-A)=23, n(AuuB)=50 , then n(AnnB) is (i) 7 (ii) 17 (iii) 27 (iv) 33

If U is the universal set with 100 elements, A and B are two sets such that n(A) = 50, n (B) = 60, n(AnnB) = 20 then n(A'nnB') =

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

A and B are two sets. If n(A) = 17, n(B) = 23, and n(AuuB) = 38 find n(AnnB) .

If n(U) = 100, n(A)=50, n(B)=20 and n(A nn B) = 10, then n{(A uu B)} =

Let n(U) = 700, n(A) = 200, n(B) = 300 and n(AuuB) = 400. Then n(A^c uu B^c) is equal to

If n(A) = 25, n(B) = 40, n(AcupB)=50 and n(B') = 25, find n(AcapB) and n(U).
