The Axiom of Choice differs from other axioms of ZF by postulating the existence of a set (i.e., a choice function) without defining it (unlike, for instance, the Axiom of Pairing or the Axiom of Power Set). Thus it is often interesting to know whether a mathematical statement can be proved without using the Axiom of Choice. It turns out that

It doesn’t say how to pick those digits, or what digits you pick, just that you can pick them, somehow. (To be clear, the axiom of choice doesn’t talk about making random choices, just a choice at An important and fundamental axiom in set theory sometimes called Zermelo's axiom of choice. It was formulated by Zermelo in 1904 and states that, given any set of mutually disjoint nonempty sets, there exists at least one set that contains exactly one element in common with each of the nonempty sets.

IIT Bombay Axiom of choice definition is - an axiom in set theory that is equivalent to Zorn's lemma: for every collection of nonempty sets there is a function which chooses an element from each set. In 1923 Hilbert asserted: The essential idea on which the axiom of choice is based constitutes a general logical principle which, even for the first elements of mathematical inference, is indispensable.

The Axiom of Choice and Cardinal Arithmetic The Axiom of Choice Axiom of Choice (AC).Every family of nonempty sets has a choice func-tion. If S is a family of sets and ∅∈/ S,thenachoice function for S is a func- tion f on S such that (5.1) f(X) ∈X for every X ∈S. The Axiom of Choice postulates that for every S such that ∅∈/ S there exists a function f on S that satisfies (5.1). How I Learned to Stop Worrying and Love the Axiom of Choice.
