- Give an example of a relation R on a nonempty set A that is symmetric and transitive, but not reflexive.arrow_forwardDoes the relation is a brother of have a reflexive property consider one male? A symmetric property consider two males? A transitive property consider three males?arrow_forwardIn each of the following parts, a relation is defined on the set of all human beings. Determine whether the relation is reflective, symmetric, or transitive. Justify your answers. xRy if and only if x lives within 400 miles of y. xRy if and only if x is the father of y. xRy if and only if x is a first cousin of y. xRy if and only if x and y were born in the same year. xRy if and only if x and y have the same mother. xRy if and only if x and y have the same hair colour.arrow_forward
