cardinality is the number of element in a set :)

The question did not ask what cardinality was but how to find it!
For a simple set with a finite number of elements it is possible to count the number of distinct elements - even though it may be time consuming. For other finite sets, such as symmetry groups, it is not always easy to identify distinct elements before counting how many there are. However, there are theoretical methods that will help in such cases.
The cardinality of an infinite group is Aleph-Null if it there is a 1-to-1 mapping with the set of integers. The cardinality is Aleph-One if the mapping is with the real numbers.
If you go beyond that, you will have studied a lot more about cardinality and will not need to ask such a question!
The cardinality of [0,1) is equal to the cardinality of (0,1) which has the same cardinality as the real numbers.
Cardinality is the number of attributes in the table.
The cardinality of a set is its size. For instance, since the set G contains 4 elements, then its cardinality is 4. So if the set has a finite number of elements (meaning it is a finite set), you can find its cardinality, otherwise you cannot (meaning it is an infinite set).
The cardinality ratio specifies the number of relationship instances that an entity can participate in.
The cardinality of a finite set is the number of elements in the set. The cardinality of infinite sets is infinity but - if you really want to go into it - reflects a measure of the degree of...

The cardinality of 15 is equal to the number of elements in the set. Since 15 is only one number, its cardinality is 1.

The cardinality of a finite set is the number of elements in the set. The cardinality of infinite sets is infinity but - if you really want to go into it - reflects a measure of the degree of infiniteness. So, for example, the cardinality of {1,2,3,4,5} is 5. The cardinality of integers or of rational numbers is infinity. The cardinality of irrational numbers or of all real numbers is also infinity. So far so good. But just as you thought it all made sense - including the infinite values - I will tell you that the cardinality of integers and rationals is aleph-null while that of irrationals or reals is a bigger infinity - aleph-one.
In Mathematics, the cardinality of a set is the number of elements it contains. So the cardinality of {3, 7, 11, 15, 99} is 5. The cardinality of {2, 4, 6, 8, 10, 12} is 6. * * * * * That is all very well for finite sets. But many common sets are infinite: integers, rationals, reals. The cardinality of all of these sets is infinity, but they are of two "levels" of infinity. Integers and rationals, for example have a cardinality of Aleph-null whereas irrationals and reals have a cardinality of aleph-one. It has been shown that there are no sets of cardinality between Aleph-null and Aleph-one.

it describes the instance of one entity is associated with each instances of an entity depending upon the range of cardinality constraints are two types they are minimum cardinality maximum cardinality
The cardinality of a set is simply the number of elements in the set. If the set is represented by an STL sequence container (such as std::array, std::vector, std::list or std::set), then the container's size() member function will return the cardinality. For example: std::vector<int> set {2,3,5,7,11,13}; size_t cardinality = set.size(); assert (cardinality == 6);
