Here's the Solution to this Question

Let X=\{a,b,c,d\}. By defenition, a biniry relation \rho on a set X is a subset of a Cartesian square X\times X. In our case,


X\times X=\{(a,a),(a,b),(a,c),(a,d),(b,a),(b,b),(b,c),(b,d),(c,a),(c,b),(c,c)(c,d),

(d,a),(d,b),(d,c),(d,d)\}.


For example, \rho=\{(a,a),(a,c),(a,d),(b,b),(b,c),(c,a),(c,b),(c,d),(d,d)\} is a binary relation on the set X.
