Chapter 8.5, Problem 57E

Let U = = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10} be the universal set. Use the following subsets of U to determine if each statement is true or false. A = {0, 1, 3, 5} and B = {2, 3, 4, 5,9} • true AUB = {3,5} • true A - B = {0, 1} ⚫ true B = {0, 1, 6, 7, 8, 10} ⚫ true An Bc • true (AUB) = {0,1} = {0, 1, 2, 4, 6, 7, 8, 9, 10} ⚫ true A x B = {(0,2), (1, 3), (3, 4), (5,5)}

Let A = {x Z | x=0 (mod 6)} and B = {x = Z | x = 0 (mod 9)}. Which of the following sentences describes the set relationship between A and B ? *Keep in mind that Ç means proper subset. AÇ B BÇA A = B AnB = 0 none of these
