WebX is a countable set, then its elements can be enumerated in a sequence; but the sequence can be finite or infinite. By a denumerable family of sets, we mean a family of sets which is denumerable. A denumerable family of sets can be indexed by N and we may write such a family as {A i} i ∈ N.We also use the same notation for a countable family, where possibly … WebExample 1: State whether the following sets are finite sets or infinite sets: a) Set A = Set of multiples of 10 less than 201. b) Set of all integers. Solution: a) Set A = Set of multiples …

WebDefinition: A countable set is a set which is either finite or denumerable. In most theorems involving denumerable sets the term denumerable can be replaced by countable. Proofs involve extending the proofs for denumerable sets by checking the cases when one or more of the sets involved are finite. Thus: Web1.3.6 Definition (a) A set S is said to be denumerable (or countably infinite) if there exists a bijection of N onto S. (b) A set S is said to be countable if it is eitherfinite or … WebProve that if S is any finite set of real numbers, then the union of S and the integers is countably infinite.
