There is only one null set. It is 'the' null set. It is a set which does not contain any numbers.

A null set is a set that contains no elements.

There is only one null set. It is 'the' null set. It is a set which does not contain any numbers. It is represented by the symbol ∅.

a set which has no elements in it is called a null set. example - A={}.

A null set is a set with nothing in it. A set containing a null set is still containing a "null set". Therefore it is right to say that the null set is not the same as a set containing only the null set.

The null set. Every set is a subset of itself and so the null set is a subset of the null set.

The null set is a set which has no members. It is an empty set.

The 'null'-content of any given field is just that. It's a 'nothing'. Example, if you create a database to hold chemical values for instance. If the values are, for example, real nubers. That would imply that any value that has 0 in it, is just that; zero. It was beeing measured, and found to contain zero. On the other hand if a value was not tested, the value of that compound should be set to 'null'. If a 'null' value isn't supported by the database a workaround is to set 'null' values to -1 (as per the example above). --

A null set is a set that does not contain any elements, an empty set.

yes

example of null set

A null or empty set is a set that does not contain any elements.

Yes the null set is a subset of every set.

Let set A = { 1, 2, 3 } Set A has 3 elements. The subsets of A are {null}, {1}, {2}, {3}, {1,2},{1,3},{1,2,3} This is true that the null set {} is a subset. But how many elements are in the null set? 0 elements. this is why the null set is not an element of any set, but a subset of any set. ====================================== Using the above example, the null set is not an element of the set {1,2,3}, true. {1} is a subset of the set {1,2,3} but it's not an element of the set {1,2,3}, either. Look at the distinction: 1 is an element of the set {1,2,3} but {1} (the set containing the number 1) is not an element of {1,2,3}. If we are just talking about sets of numbers, then another set will never be an element of the set. Numbers will be elements of the set. Other sets will not be elements of the set. Once we start talking about more abstract sets, like sets of sets, then a set can be an element of a set. Take for example the set consisting of the two sets {null} and {1,2}. The null set is an element of this set.

empty set or null set is a set with no element.

It is possible to specify a condition which can't be fulfilled, for example, the intersection of two sets that have no element in common. The result would have no elements. Not allowing this kind of operation would be more complicated than defining a null set (or empty set) that has zero elements.

An empty set is a set that has no elements. A null set has 0 elements. This may sound the same but just think of it as this: 0 is a number, as in null, and empty set no elements

Yes. A null set is always a subset of any set. Also, any set is a subset of the [relevant] universal set.

-- The null set is a set with no members. -- So it has no members that are absent from any other set.

The definition of subset is ; Set A is a subset of set B if every member of A is a member of B. The null set is a subset of every set because every member of the null set is a member of every set. This is true because there are no members of the null set, so anything you say about them is vacuously true.

Null Set is also called Void Set. Some books have even called it Empty Set.

That's a null set. All multiples of 10 are even.

even though its carnality is 0 one of its properties says that the only subset of the null set is the empty set * * * * * Carnality refers to sexual desires and I would be greatly surprised if the null set had any of those! The number of subsets of a set whose cardinality is C(S) is 2C(S). The cardinality of the null set is, as the answer was trying to say, 0. So the number of its subsets is 2C(S) = 20 = 1. A null set has one subset - which is also a null set.

The Null Set is a Set.
