Let A and B be Two Given Finite Sets Such That n(A) =20, n(B)=28, and n(A ∪ B) =36, Find n(A ∩ B).

If f(x) =x^n and if f’ (1) = 10, find n.

If n(A)=1000, n(B)=500 and if n(AnnB) ge 1 and n(AuuB)=p then

If A and B are two sets such that : n(A)=20, n (A uu B)=42 and n (A nn B)=4 . Find: n (B), n (A - B) and n (B - A).

If A and B are two sets such that : n(A)=17, n (A uu B)=38 and n (A nn B)=2 . Find: n (B), n (A - B) and n (B - A).

Let n(U)=500. If A and B are such that n(A)=200, n(B)=300 and n(AcapB) =100 then n(A' cap B') is equal to:

Given n(U) = 20, n(A) = 12, n(B) = 9, n(AnnB) = 4, where U is the universal set, A and B are subsets of U, then n((AuuB)') equals
