Find the cardinality of the given set:
A=a,e,i,o,u.
Finding the cardinality of the given set.
The number of distinct elements in a set is called its cardinality.
In the given set A, there are 5 distinct elements.
Hence, the cardinality of the given set Ais 5.
B=x:xamultipleof3,x≤20.
The cardinality of a universal set, set A and set B are represented as n(U), n(A), n(B) respectively. Find the cardinality of the set which does not contain elements of set A and set B.
The cardinality of two disjoint sets A and B is in the ratio 2:1. If the cardinality of the union of these sets is 45, find the cardinality of the two sets.
