If `n(AcupB)=18 `n(A cap B)=5`,n(B -A)=3`,then find `n(A cap B)`

Two sets A and B are such that n(A cup B)=21,n(A' cap B')=9,n(A cap B)=7 find n(A cap B)'

If n(mu )= 40, n(A' cap B')= 6 , n(A cap B')= 10 and n(B cap A)= 16,"then find" n(A cap B)

If n(A) = 20 , n(B) = 30 and n(A cup B )=45 then find n(A cap B)

For any three sets n(A cup B cup C)=60, n(A)=25, n(B)=20, n(C)=15, n(A cap B)=10, n(B cap C)=7, n(A cap C)=3," then "n(A cap B cap C) is.........

(i)If n(A)=25, n(B)=40, n(A cup B)=50 and n(B')=25," find "n(A cap B) and n(U) . (ii) If n(A)=300, n(A cup B)=500, n(A cap B)=50 and n (B')=350 , find n(B) and n(U) .

If A and B are two sets such that n(A) = 17,n(B)=23 and n(A cup B) = 38 , then find n(A cap B) .

If A and B are two sets such that n(A) = 17,n(B)=23 and n(A cup B) = 38 , then find n(A cap B) .

If n (p(A)) = 1024, n (A cup B) = 15 and n (P (B)) = 32, then find n (A cap B).

If n(A)=12 and n( A cap B )=5, then findn(A-B)=……..
