n(A)=2,n(B)=7, `n(A cap B)=1 and n (A cup B)`?

What is the relation between n(A), n(B), n(A cap B) ""and"" n(A cup B) ?

IF n(A)=8,n(B)=6, n(A cap B)=3, then n(A cup B)=………

If A = {letters of word ORANGE } and B = { letters of word MANGO} , find n(A) , n(B) , n(A cup B ) and n (A cap B)

n(A)=10,n(B)=4,n(A cap B)=2 then n( A cup B )=

IF n(A)-8,n(B)=3, n(A cap B)=2, then n(A cup B)=………….

If n(U)=70, n(A)=25, n(B)=30, n(A cap B)=5," then "n(A cup B)' is..........

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))

If n(A)=50, n(B)=35, n(A cap B)=5," then n(A cup B) is equal to .........."

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)).
