what type of relationship is indicated by the set of ordered pairs
Repetition of the elements are immaterial. The number of elements in a set '$A$' is denoted as $|A|$, is called the cardinality of the set, a set with no elements. Relationship between sets can be represented by venn diagrams. A relation describes certain properties of things and is a set of ordered pairs. It is a subset of ordered pairs drawn from the set of all possible ordered pairs. $R$ is a relation if. $R \subseteq {(x, y) |x\ \epsilon \ X,y\ \epsilon Y}$. Here Domain is $X$ and Codomain is $Y$.
