WebA = {coat, hat, scarf, gloves, boots}, where A is the name of the set, and the braces indicate that the objects written between them belong to the set. Every object in a set is unique: The same object cannot be included in the set more than once. Let's look at some more examples of sets. Example 2: What is the set of all fingers? WebApr 17, 2024 · Set Equality, Subsets, and Proper Subsets In Section 2.3, we introduced some basic definitions used in set theory, what it means to say that two sets are equal and what it means to say that one set is a subset of another set. We need one more definition. Definition: proper subset Let A and B be two sets contained in some universal set U.

If A = { 1, 2, 3 } and B = { a, b, c } then A and B are equivalent. Since the empty set is unique – ∅ is the only set having 0 elements – it follows that there are no other sets equivalent to it. margaret richardson go fund me
