For any two set A and B, `n(A)+n(B)-n(A capB)=`

For any two sets A and B prove that n(A-B)=n(A)-n(AnnB) .

For any two sets A and B, prove that : (i) (A capB)cup(A-B)=A (ii) A cup(B-A)=A cupB .

For any two sets A and B, prove that : (i) (A capB)cup(A-B)=A (ii) A cup(B-A)=A cupB .

For any two sets A and B, prove that : (i) (A-B)cupB=AcupB (ii) (A-B)capB=phi

For non null sets A and B if n(A) =16,n(B) = 14 , n(A cup B) = 25 then n(A capB)= .........

If A and B are two sets so that n(B-A) =2n (A-B) =4n(A cap B) and" if "n(A cup B)=14 , then find n(P(A)).

For any two sets A and B, prove that : (i) A - (A-B)=A capB (ii) A cap (A' cup B) = A cap B .

Form two sets A and B such that n(A) = 3, n(B) = 4 and n(A uu B) = 5.
