Cardinality of Sets with Repeated Elements | Set Theory

How do repeated elements in a set effect its cardinality? We go over this with examples in today's set theory video lesson. The short answer is that repeated elements do not effect the cardinality of a set, because sets are defined only by the distinct elements they contain. We will briefly discuss multisets, where repeated elements do matter. #SetTheory
