For example, if a pencil set has 10 pencils in it, then the cardinality of pencils is 10.Cardinal Number of a SetThe number of elements in a set is known as the cardinal number of that set. If A is a finite set and it has N elements, then the cardinal number of set A is given...

Using a greedy algorithm, we conclude that there is a set of cardinality , such that each set with , intersects for some , or in other words that whenever . In particular, This implies that there exists a subset of with , and an element for each , such that for all . Note we...
Combinatorially, the identity (2) follows from the fact that given any injections and with total image of cardinality , one has , and furthermore there exist precisely triples of injections , , such that and . Example 1 When , one has which is just a restatement of the identity Note that...
The number of elements in the set are denoted by n(A) where A is a set. Example: $\text{A} = \left\{1, 4, 9, 16, 25, 36, 49, 64, 81, 100\right\}$. $n(A) = 10$. The other word used for the number of elements in the set is called its cardinality. ...
A subset B⊆A can be defined by deciding whether each individual element of A is or is not to be included in B. The cardinality of the power set is therefore equal to |P(A)|=2|A|Answer and Explanation: The cardinality, meaning the number of elements, of the sets A and B are ...
Denoted by {eq}n(A) {/eq} or {eq}|A| {/eq}, the number of objects belonging to a set is called the cardinal number or cardinality of the set. Thus, the cardinality of set {eq}A {/eq} is {eq}4 {/eq} as there are four letters in ...
The representation of a set is done by using the letters of English alphabets. A set can have a finite or infinite number of elements. Example of the set- Set of prime numbers- $$P = \left \{2,3,5,7,11,...\right \} $$ Prime of a ...
