Tags Cardinality Discrete Discrete math Sets This proves that there is a one-to-one correspondence between (0,1) and (1,∞), and therefore, they have the same cardinality.In summary, the conversation discusses the concept of infinite sets having the same cardinality, using the example of a ...
MHBInequality of Cardinality of Sets I am working on a proof problem and I would love to know if my proof goes through: If $A, B$ are sets and if $A \subseteq B$, prove that $|A| \le |B|$. Proof: (a) By definition of subset or equal, if $x \in A$ then $x \in B$...
