cardinality examples
What is cardinality example?
Cardinality refers to the number that is obtained after counting something. Thus, the cardinality of a set is the number of elements in it. For example, the set {1, 2, 3, 4, 5} has cardinality five which is more than the cardinality of {1, 2, 3} which is three.
What is the cardinality of a finite set?
If a set A = {1, 2, 3, 4}, then the cardinality of the power set of A is 2 4 = 16 as the set A has cardinality 4. The cardinality of a set is nothing but the number of elements in it. For example, the set A = {2, 4, 6, 8} has 4 elements and its cardinality is 4. Thus, the cardinality of a finite set is a natural number always.
What is the cardinality of a power set?
If a set A has n elements, then the cardinality of its power set is equal to 2 n which is the number of subsets of the set A. In general, we can say that the cardinality of a power set is greater than the cardinality of the given set. If a set A = {1, 2, 3, 4}, then the cardinality of the power set of A is 2 4 = 16 as the set A has cardinality 4.
What is the cardinality of an uncountable set?
An uncountable set always has a cardinality that is greater than ℵ 0 and they have different representations. For example, the cardinality of the uncountable set, the set of real numbers R, (which is a lowercase "c" in Fraktur script). To summarize: The cardinality of any countable infinite set is ℵ 0.
