Detailed explanation-1: -A set which does not contain any element is called an empty set, or the null set or the void set and it is denoted by ∅ and is read as phi. In roster form, ∅ is denoted by . An empty set is a finite set, since the number of elements in an empty set is finite, i.e., 0.
Detailed explanation-2: -The empty (or void, or null) set, symbolized by or Ø, contains no elements at all.
Detailed explanation-3: -Answer: the set 0 is not an empty set .. it has only one element which is 0 . But the set Ø is an empty set .
Detailed explanation-4: -An empty set is a finite set since its cardinality is defined and is equal to 0. As we know, a set is said to be infinite if the number of elements in it are infinite, i.e. its cardinality is ∞ or not defined, whereas a finite set contains a countable number of elements.
