Nettet26. nov. 2024 · Set B is Singleton Set since there is only one element whose square is 9 and it is 3. 3. B = {z : z is a even prime number} Set B is Singleton Set as 2 is the only even prime number. Finite Set. Any Set that is either empty or contains a finite number of elements i.e. countable elements is called a Finite Set. Example Nettet29. sep. 2024 · If card ( A) > card ( B), then any function f: A → B is not an injection. Theorem 9.10. Let A and B be sets. 1. If A is infinite and A ≈ B, then B is infinite. 2. If A is infinite and A ⊆ B ,then B is infinite. Theorem 9.13. The set Z of integers is countably infinite, and so card ( Z) = ℵ 0 .
