Those are called the elements of the set.
That is called the average or mean.
a set which has no elements in it is called a null set. example - A={}.
This is called the complement of the set.
It's called an infinite set.
Those are called the elements of the set.
The difference between joint sets and disjoint sets is the number of elements in common. A disjoint set, in math, does not any elements in common. A joint set must have at least one number in common.
A set is a collection of objects called ELEMENTS OR MEMBERS.
Members.
Empty set or null set
An 'Empty Set' or a 'Nul Set'.

There are various types of sets based on the relationship between their elements. Some common types include: Empty set: A set containing no elements. Singleton set: A set with only one element. Finite set: A set with a countable number of elements. Infinite set: A set with an uncountable number of elements. Subset: A set where all elements are also elements of another set. Proper subset: A subset that is not equal to the original set. Universal set: A set that contains all elements under consideration. Disjoint set: Sets that have no common elements. Power set: A set consisting of all possible subsets of a given set.
In mathematics, a finite set is a set that has a finite number of elements. For example, (2,4,6,8,10) is a finite set with five elements. The number of elements of a finite set is a natural number (non-negative integer), and is called the cardinality of the set. A set that is not finite is called infinite. For example, the set of all positive integers is infinite: (1,2,3,4, . . .)
This is called the complement of the set.
Allowing sets with zero elements simplifies things, in the sense of not requiring all sorts of special cases. For example: the intersection of two sets is another set (which contains all items that are elements of BOTH original sets). Period! If you allow the empty set, there is no need to alter the definition of an intersection, to consider the special case that the sets have no elements in common.
