`" If "n(mu)=30,n(A)=10.n(B)=15." then "n((mu-A)')=`

If n(A)=10,n(B)=15 and n(A uu B)=x

If n(mu)=100,n(A)=50,n(B)=20 and n(A cap B) =10, then n[(AcupB)]=

Two sets A and B are such that n(A cup B)=21 ,n(A)=10,n(B)=15 then find n(a cap B) and n(A-B)

If A and B are two sets such that n(A uu B)=36 , n(A nn B)=16 and n(A-B)=15 then n(B) is equal to

If n(A)=50,n(B)=20 and n(A nn B)=10 then n(A Delta B) is

If n (A)=10, n(B)=21 and n(A nn B)=5 , then find n(A uu B) .

If n(A)=10,n(A cap B)=5 and n(A cup B) =35 then n(B) =____.

If n(u)=100,n(A)=50,n(B)=20 and n(A nnB)=10, then n{(AuuB)^©}

If n(AuuBuuC)+n(AuuBuuC)'=50,n(A)=10,n(B)=15,n(C)=20,n(AnnB)=5,n(BnnC)=6.n(CnnA)=10and n(AnnBnnC)=5,then n(AuuBuuC)' is equal to
