QUESTION 1: a) Given a set A = {13,453}. i. Define a relation R on setA such thataRb where [a+b] is an even number. ii. Determine vmetherthe relation R is reflexive, symmetric, and transitive and state the reason(s) for each relation. iii. Determine whether the R is equivalence relation and state the reason(s] {7' marks) b) Given A={2, 3, 5} and R={[2,2},{3,3], (5,5), (3,5),{5,3)} is equivalence relation on set A. i.
