WebQ − the set of all rational numbers. R − the set of all real numbers. W − the set of all whole numbers. Cardinality of a Set. Cardinality of a set S, denoted by $ S $, is the number of elements of the set. The number is also referred as the cardinal number. If a set has an infinite number of elements, its cardinality is $\infty$. WebThe cardinality of the empty set is the number of elements.
