2.3 Infinite sets and cardinality
... • The cardinality of a finite set is defined as the number of elements in it. • Two sets A and B have the same cardinality if (and only if) it is possible to match each element of A to an element of B in such a way that every element of each set has exactly one “partner” in the other set. Such a match ...

Exercises about Sets
... Write the sets with the roster method, set builder notation, and interval notation whenever possible. How many elements are in each set? Sketch the graph of each set on a Real number line. Use Venn diagrams to show the relationships between the sets involved in each question. a) N (2,5) b) N (-2 ...
