"WebA relation R defined on a set A with n elements has ordered pairs of the form of (a, b). Now, we know that element 'a' can be chosen in n ways and similarly, element 'b' can be chosen in n ways. This implies we have n 2 ordered pairs (a, b) in R. Also, if (a, b) is in R, then for a symmetric relation, (b, a) is forced to be in R. " - Ordered pairs in a relation
