-C Countable sets:1 A set is called countable (or countably infinite) if it has the same cardinality as N. Equivalently, a set A is countable if it can be enumerated in a sequence, i.e., if all of its elements can be listed as a sequence a1,a2,... . A set is called uncountable if it is infinite and not countable.
