Prove that the relation is an equivalence relation, and (2) describe the distinct equivalence classes of each relation:A is the set of all students at your college. a. R is the relation defined on A as follows: For all x and y in A, xRy ⇔ x has the same major (or double major) as y. (Assume "undeclared" is a major.) b. S is the relation defined on A as follows: For all x, y ∈ A, xSy ⇔ x is the same age as y.
