If A and B are disjoints sets with n(A) = 3 and n (B) = 6. Compute `n{(A-B)uu(B-A)}`

If A and B are two disjoint sets, then n(AcupB) is equal to:

If A and B are two sets, then A nn (A uu B) equals

If A and B are any two sets, prove that : (A-B) uu B =A uu B .

If A and B are sets and A uu B = A nn B then

If A and B are two sets ,then (A-B)uu(B-A)uu(AnnB) equals

Let A and B be two sets such that n(A) = 3 and n(B) = 2. If (x, 1), (y, 2),(z, 1) are in A xx B , find A and B. where x, y and z are distinct elements.

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 A and B be two finite sets such that n(A) =85, n(B) = 65and n(A ∪ B) = 135, find n(A ∩ B)?

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:
