Suppose every item is packed in one or another of grocery bags. Describe a relation that represents the packing of the items into the bags. Is this relation reflexive? symmetric? transitive? Explain. "Example for Relation: R = {(item 1 in bag 1, item2 in bag2), (item 3 in bag 1, item 4 in bag 2)....} "

Why are the numbers modulo n a set of equivalence classes?

How could a collection of disjoint sets not make an equivalence relation?
