Math - the elements of a universe not contained in a given set?
This is called the complement of the set.
What is the defatitation of subset?
a set of which all the elements are contained in another set.
What the universal set and a subset?
It is the set of all elements we are considering or dealing with in a given problem. We use a capital U or sometimes capital E to mean the universal set. Now take ANY two sets, A and B. If every single element of set A is contained in set B, we say A is a subset of B. The empty set is a subset of every set. Every set in contained in the universal set, so they are all subset of it.
How many subset are there in given set?
If the set has n elements then it has 2n subsets.
What is the largest equivalence relation on a set A?
An equivalence relation on a set is one that is transitive, reflexive and symmetric. Given a set A with n elements, the largest equivalence relation is AXA since it has n2 elements. Given any element a of the set, the smallest equivalence relation is (a,a) which has n elements.

How can the concept of a vertex cover be related to the concept of a set cover?
The concept of a vertex cover in graph theory is related to the concept of a set cover in combinatorial optimization. In a vertex cover, the goal is to find the smallest set of vertices that covers all edges in a graph. In a set cover, the objective is to find the smallest collection of sets that covers all elements in a given universe. Both problems involve finding the minimum number of elements (vertices or sets) needed to cover all the elements (edges or universe) in a system.

Can a subset of an infinite set be finite?
A subset of some set X is, by definition, any set whose elements are entirely contained in X. So the answer is yes. As an example, take your infinite set, and select 3 or 10 or any finite number of your favorite elements in this set. The set of your chosen elements is a finite subset of the infinite set.
Difference between Union and Set Intersection Operation?
union means to group the given sets. where as intersection means to pick out the common elements from the given sets. if set a has 1,2,3 elements and B has 1,2,3,4,5. then its union will have 1,2,3,4,5 as its elements. and its intersection will have 1,2,3 as its elements.
Why is the empty set a subset of all sets?
A subset of a given set is simply any set, all of whose elements are contained in the other. Since the empty set has no elements, all of its elements are in any other set! It sounds weird, but that's the way logic works. To put it another way, a set A is NOT a subset of B if there is some element x of A that is not in B. Since the empty set has no elements that are not in your given set, we can't say it is NOT a subset. That means that it is. To select a subset, we must look at each member of the set and decide whether to keep it. If we say "yes" to every member, we have the set itself; if we say "no" to all of them, we have the empty set. We could choose to exclude these from the definition of subset, but it makes a lot of things easier if we include them. That way there are no special cases to deal with when we state theorems.
What is an absolute complement?
An absolute complement is the set which includes exactly the elements belonging to the universal set but not to a given set.
What are subsets in math?
A set of which all the elements are contained in another set. The set of even numbers is a subset of the set of integers.
What is a set that is contained in a larger set?
The set contained in another set is termed as a sub-set.
