Given n(U) = 20, n(A) = 12, n(B) = 9, `n(AnnB)` = 4, where U is the universal set, A and B are subsets of U, then `n((AuuB)')` equals

Given n(U) = 20, n(A) = 12, n(B) = 9, n(AnnB) = 5, where U is the universal set, A and B are subsets of U, then n((AuuB)') equals

Given n (U) = 20, n (A) =12, n (B) = 9, n (A nnB) = 4, where U is the universal set, A and B subsets of U, then n [(A uu B) ^c ] equals to : a)17 b)9 c)11 d)3

Given n(U)=20, n(A)=12, n(B)=9, n(A cap B)=4, where U is the universal set, A and B are subsets of U, then n[(A cup B)']=

Consider n(U)=20 , n (A) =12, n(B)=9, n(A nn B) =4, where U is the universal set, A and B are subsets of U, then n((A uu B)^c) =

Given n(S) =20, n (A) =12, n(B)=9, n(A nnB)=4 where S is the universal set, A and B are subsets of S, then n[(A uuB)^( C)] is equal to-

Given n(U)=20, n(A)=12, n(B)=10, n(A cap B)=4 where U is the universal set, A and B are subsets of U then n( (A cup B)^(c) )=

If n(U) = 50, n(A) = 20, n(AuuB)' = 18 then n(B- A) is

If n(U)=50, n(A)=24, and n(B)= 30 where U is the universal set, then find (i) The greatest value of n(A cup B) (ii) The least value of n(A cap B)
