to prove the Statement. (Assume that Statement: For all sets A, B, and C, (A - B) n (C - B) = (A N C) – B. Proof: Suppose A, B, and C are any sets. [To show that (A - B) N (C – B) = (A N C) - B, we must show that (A – B) n (C – B) C (A N C) – Band that (A n C) - BE (A - B) n (C - B).] Part 1: Proof that (A - B) N (C – B) C (A N C) - B Consider the sentences in the following scrambled list. Thus x E ANC by definition of intersection, and, in addition, x € B. Therefore x E (AN C) - B by the definition of set difference. By definition of set difference, x E A - Band x EC - B. By definition of intersection, x E A and x EB and x E C and x € B. By definition of intersection, x E A - B and x EC - B. By definition of set difference, x E A and x € B and x E C and x € B. To prove Part 1, select sentences from the list and put them in the correct order. 1. Suppose x € (A – B) N (C – B). 2. --Select--. 3. ---Select-. 4. ---Select--- 5. ---Select-. 6. Hence, (A - B) n (C - B) S (AN C) - B by definition of subset. Part 2: Proof that (A N C) – BC (A – B) N (C – B) Consider the sentences in the following scrambled list. By definition of intersection, x € (A - B) n (C - B). By definition of intersection x E AnC and x € B. By definition of set difference, x E A and x E C. By definition of set difference x E ANC and x ¢ B. Hence both x E A and x € B and also x E C, and x € B. So by definition of set difference, x E A - Band x E C - B. Thus, by definition of intersection, x E A and x € C, and, in addition, x ¢ B. To prove Part 2, select sentences from the list and put them in the correct order. 1. Suppose x E (AN C) - B. 2. ---Select--. 3. ---Select--- 4. ---Select.-. -Select--- 6. --Select--- 7. Hence, (A N C) - BE (A - B) n (C - B) by definition of subset. 5.
