Not necessarily. The odd integers and the even integers are two infinitely large sets. But their intersection is the null (empty) set.
Disjoint sets are sets whose intersection, denoted by an inverted U), produces the null or the empty set. If a set is not disjoint, then it is called joint. [ex. M= {1,2,A} N = {4,5,B}. S intersection D is a null set, so M and N are disjoint sets.
Because they are disjoint, (ie. they contain none of the same elements) their intersection (what they both share in common) is the empty or null set.
A null set is a set that does not contain any elements, an empty set.
The terms are usually used to describe sets that contain no elements or empty sets.
A null set is an empty set, or a set with no elements in it. Although that may sound pointless, its uses are similar to those of 0 in arithmetic.

The concept of closure: If A and B are sets the intersection of sets is a set. Then if the intersection of two sets is a set and that set could be empty but still a set. The same for union, a set A union set Null is a set by closure,and is the set A.
Not necessarily. The odd integers and the even integers are two infinitely large sets. But their intersection is the null (empty) set.
A null set, also known as an empty set, is a set with no elements. It is denoted by the symbol Ø or { } and is considered a subset of all sets. The cardinality of a null set is zero.
A null or empty set is a set that does not contain any elements.
Disjoint sets are sets whose intersection, denoted by an inverted U), produces the null or the empty set. If a set is not disjoint, then it is called joint. [ex. M= {1,2,A} N = {4,5,B}. S intersection D is a null set, so M and N are disjoint sets.
A criteria that searches for fields that are not empty is called a "not null" criteria. This criteria is used to filter out records where a specific field does not have a null or empty value.
Because they are disjoint, (ie. they contain none of the same elements) their intersection (what they both share in common) is the empty or null set.
A null set is a set that does not contain any elements, an empty set.
The null set is a set which has no members. It is an empty set.
