Question

what is null set??????????​

Answer 1

In mathematical analysis, a null set is a set that can be covered by a countable union of intervals of arbitrarily small total length. The notion of null set in set theory anticipates the development of Lebesgue measure since a null set necessarily has measure zero. 

Answer 2

Step-by-step explanation:

Here ur answer

the null set, also called the empty set, is the set that does not contain anything. It is symbolizedor { }. There is only one null set. This is because there is logically only one way that a set can contain nothing.

The null set makes it possible to explicitly define the results of operations on certain sets that would otherwise not be explicitly definable. The intersection of two disjoint sets (two sets that contain no elements in common) is the null set.
