If n(A)= 3 and n(B)= 6 and A ⊆ B, then the number of elements in(A∩B) equals

If a set A has 3 elements and B has 6 elements such that A⊆BIf a set A has 3 elements and B has 6 elements such that A⊆Bthen the number of elements in A∩B=?

If two sets are such that n (A intersection B) = ½ (AUB) = 6. Then a total number of elements in these sets is?A.9B.12C.16D.18

For disjoint sets A and B, n(A) = 3 and n(B) = 5 then n(A ∩ B) is
