The Axiom of Extensionality in Set Theory states that a set is completely determined by its elements, or, in other words, that two sets are equal (i.e. the same set) if they contain the same elements. In this sense, the "extension" of a set is simply its content, which is all you need to identify it. Share. Cite.

WebSolved basic word problems on sets: 1. Let A and B be two finite sets such that n (A) = 20, n (B) = 28 and n (A ∪ B) = 36, find n (A ∩ B). Solution: Using the formula n (A ∪ B) = n (A) + n (B) - n (A ∩ B). then n (A ∩ B) = n (A) + n (B) - n (A ∪ B) = 20 + 28 - 36 = 48 - 36 = 12 2. WebELEMENTARY SET THEORY DONU ARAPURA 1.
