4. For the given collection of sets {[-1,3). [-1,2), [-1,23). [-1,2),...} define a set A, for each nEN such that the indexed collection {A} is precisely the given collection of sets. Then answer the questions. A5 = 00 U An n=1 An = Is {An}1 a pairwise disjoint collection of sets? Justify your answer.
