no. A subset would have to allow for values in its parent which are not in its self.
NO- by definition a set is not a proper subset of itself . ( It is a subset, but not a proper one. )
Let A be the set {1,2,3,4} B is {1,2} and B is a proper subset of A C is {1} and C is also a proper subset of A. B and C are proper subsets of the set A because they are strictly contained in A. necessarily excludes at least one member of A. The set A is NOT a proper subset of itself.
A is a subset of a set B if every element of A is also an element of B.
The line, itself, is a subset (though not a proper subset). A ray is a subset of a line with one end-point which extends in only one direction. A line segment is a subset of a line with two end points. A point is a subset of a line.
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.
Because every set is a subset of itself. A proper subset cannot, however, be a proper subset of itself.
Every set contains the empty set. Every set is a subset of itself.
NO- by definition a set is not a proper subset of itself . ( It is a subset, but not a proper one. )
The null set. Every set is a subset of itself and so the null set is a subset of the null set.
No. The empty is the a subset of every set and every set is a subset of itself.
The only subset of an empty set is the empty set itself.
Yes,an empty set is the subset of every set. The subset of an empty set is only an empty set itself.
yes, if the set being described is empty, we can talk about proper and improper subsets. there are no proper subsets of the empty set. the only subset of the empty set is the empty set itself. to be a proper subset, the subset must be strictly contained. so the empty set is an improper subset of itself, but it is a proper subset of every other set.
A subset of a set S can be S itself. A proper subset cannot.
If you have a set S, the only improper subset of S is S itself. An improper subset contains all elements of S and no others. It is therefore equivalent to S. For example if S ={1,2,3} then the improper subset is {1,2,3}, and an example proper subset is {1,2}.
An improper subset of a set is a subset that includes the set itself. For example, if we have a set ( A = {1, 2, 3} ), then the improper subsets of ( A ) are ( A ) itself, which is ( {1, 2, 3} ), and the empty set ( \emptyset ). The term "improper subset" is often used to distinguish between proper subsets (which do not include the entire set) and the set itself.
A set "A" is said to be a subset of of set "B", if every element in set "A" is also an element of set "B". If "A" is a subset of "B" and the sets are not equal, "A" is said to be a proper subset of "B". For example: the set of natural numbers is a subset of itself. The set of square numbers is a subset (and also a proper subset) of the set of natural numbers.
