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(mu) = 200 and n( A' cap B) = 120, then find n(A cup B)

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

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

If n(A) =5, n(A cup B) = 9 , n(A cap B)=2 , find n(B).

If n(A )= 20 n(A cap B) = 10,and n(A cup B)=70 then find n(B).

n(U)= 150, n(A)= 75, n(B)= 57, n(C )= 65, n(A cap B)=37, n(A cap C)= 36, n(B cap C)= 25" and "n(A cap B cap C)= 19 , then find n(A cup B cup C), and "n(A' cup B' cup C') .

If n(A cap B) = 3 and n (A cup B) = 10 then find n (P (A triangle B))
