Answer 1

1.Yes. A subsetA is the one whose few or all elements belong to another setB, not necessary that B is a subset of A.If so, the sets are equal. Since an empty set contains no element, it is also a subset.
2.Yes. Like I stated before, if set B contains n elements, and setA is the subset of set B, it can have all the elements of setB
3. If the two sets are given, compare the elements of the set, you must find atleast one element in each set that is not present in the other set. This proves that the sets are not subsets if each other.
