WebbSuppose that A and B are sets with the same cardinality (that is, there is a bijection f : A → B). Then F : P (A) → P (B) is defined by F (C) = { f (a) : a in C} for C in P (A). Then, F is a bijection. Using this to prove that: For any set A, P (A) is either finite or uncountable. (Hint: split into two cases: A is finite and A is infinite ... WebbAnswer (1 of 3): If a collection doesn’t have a cardinality it is a proper class and not a set. Sets and proper classes are both types of classes.

Two sets are said to have the same cardinality if there exists a one-to-one correspondence between the elements of the two sets. In other words, if we can match each element in set A with a unique element in set B, and vice versa, then the sets have ... guangzhou liuhua fashion wholesale market
