We have the following sets : A={x,y,z}, B={1,2}. What are all the possible subsets of AxB?

Let A = {1, 3, 5, 7, 9},  B = {3, 6, 9}, and  C = {2, 4, 6, 8}. (d) A ∩ C:  (e) A − B:  (f) B − A

Let U= {1,2,3,4,5,6,7,8,9}  A= {2,4,6,8}  B= {1,2,3,4} and C= {5,7,9}  Give a set, D, that is equivalent to C, but not equal to C.  I am confused on the difference and how to proceed with this.

The difference of two sets, A – B, is defined as the set containing all elements of A except those in B. That is, A - B = AN B'. Find A - B for the pair of sets if U = {1, 2, 3, 4, 5, 6, 7, 8, 9}. (Enter your answer in roster notation. Enter EMPTY or Ø for the empty set.) A = {3, 5, 9} and B = {2, 4, 6, 7, 8, 9} A - B =

A universal set U with 156 elements has been partitioned into three subsets, A, B, and C. If B is 5 times the size of A and C is 4 times the size of B, then how many elements are in B? (A) 7 (B) 30 (C) 36 (D) 120 (E) 156 (F) 5 (G) 31 (H) 6 OA OB D. O E OF H.

Use A = {5, 6, 7, 8, 9) and B = {3, 6, 7, 8} to find the set A n B. AnB = {} (Use a comma to separate answers as needed.)
