yes it does it has great service
No.
It is empty set
It is an empty set.
1. Null set or Empty set 2. Singleton set 3. Pair set
The empty set is a finite set.
The empty set is a subset.
yes, technically.

Easily. Indeed, it might be empty. Consider the set of positive odd numbers, and the set of positive even numbers. Both are countably infinite, but their intersection is the empty set. For a non-empty intersection, consider the set of positive odd numbers, and 2, and the set of positive even numbers. Both are still countably infinite, but their intersection is {2}.
Use set builder notation to represent the following set.{... -3, -2, -1, 0}
Yes,empty set or void set or null set is a subset of every set.In order to know the number of subsets of any set, first of all count the number of elements in the set and take the number of elements as the exponent of 2, then you will get the number of subsets of any set.
