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 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 finite sets with n(A) =3 and N(B)=6 then find n(AxxB)

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

If A and B are finite sets, such that A sub B , then n(A uu B) is equal to "………"

If n elements are common in sets A and B, then prove that n^(2) elements will be common in the set AxxB and BxxA .

Choose the correct answer: 1. If A,B and C are three sets and U is the universal 6 set such that n(U)=700,n(A)=200,n(B)=300 and n(A n B)=100. Find n(A' ' B')
