Do not use Venn diagrams in this question. Suppose A and B are sets. (a) Use the definition of equality of sets to prove that A – B = AN B. (b) Use either the definition or set identities to prove that AN (B – A) = 0.
3. Show that if A and B sets then A – B = ANB (Note that: Using Venn Diagram is not accepted!)
1. Prove the following statements about sets A and B. A B AN B
6. Use a direct proof technique to prove the following theorems: The sets A, B, and C are arbitrary subsets of some universal set U. Prove that (C – A) U (C – B) = C – (An B).
Let A1,A2,.......,An be countable sets. Prove that A1 x A2 x.............An = { a1, a2, .......,an)| ai belongs to Ai, for every i=1,2,.......n}
Let A and B be sets. Prove that A – B = AUB.
Suppose A,B and C are sets with C∕= ∅. Prove that if A×C= B×C, then A= B. Whyis it necessary that we specify that C∕= ∅?
3. Consider the sets A = {0, 1} Which is the following statements is TRUE? (a) 0 EAN B (b) 0 € An B (c) {0,1} CANB (d) All of the other statements are false. and B = {CC is a subset of {0, 1}}.
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 =
(10) Write each of the following sets in the form of listing its elements (i.e. in the form {a,b,c} to denote the set containing the three elements a, b and c.) ) What is P({0})? P(A), where A:= {b, A, &}. }
