Document Summary

Instructions in a closed backpack or otherwise hidden from view during the exam: books, notes, and electronic devices may not be used. Problem 1 (9 points). (cid:83) correct. (a) for n = 1, 2, 3, . de ne the inverval an = [1/n, n]. Rewrite the union of intervals n n an as an interval. For each statement below, circle t or f according to whether the statement is true or false. You do not need to justify your answers. T f (p = r) (q = r) logically implies (p q) = r. T f for all a, b, c, d, if {a, b} = {c, d} and a = c, then b = d. T f for all sets a, b, c, d, and u , if {a, b, c, d} is a partition of u , then so is {a b, c d}.
