If `A;B and C` are finite sets and U be the universal set then No. of elements in exactly two of the sets `A;B;C` is =`n(AnnB)+n(BnnC)+n(CnnA)-3n(AnnBnnC)`

If A;B and C are finite sets and U be the universal set then No.of elements in exactly two of the sets A;B;C is =n(A nn B)+n(B nn C)+n(C nn A)-3n(A nn B nn C)

If A;B and C are finite sets and U be the universal set then No.of elements in exactly one of the sets A;B;Cquad =n(A)+n(B)+n(C)-2n(A nn B)-2n(B nn C)-2n(C nn A)+3n(A nn B nn C

If A;B and C are finite sets and U be the universal set then n(A-B)=n(A)-n(A nn B)

If A;B and C are finite sets and U be the universal set then n(A Delta B)=n(A)+n(B)-2n(A nn B)

If A;B and C are finite sets and U be the universal set then n(A'nn B')=n((A uu B)')=n(U)-n(A uu B)

If A;B and C are finite sets and U be the universal set then n(A'uu B')=n((A nn B)')=n(U)-n(A nn B)

If A and B are two finite sets and n(A)=5,n(B)=6 then the minimum number of elements of the set A cup B is

If A and B are any two finite sets then n (A) + n (B) is equal to

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 A and B are two finite sets such that A nn B != phi , then n (A uu B) =
