For questions 1 - 3, write the set theory counterpart for each logic statement. 1. ~ v b 2. ~(w \~r) 3. ~(~a C) For problems 4 - 6 circle the appropriate word, "valid" or "invalid". 4. If the intersection of the premises of an argument is regions II, III, and V and the conclusion of the argument is regions II, III and V then the argument is VALID INVALID 5. If the intersection of premises of an argument is region IV and V and the conclusion of the argument is region V then the argument is VALID INVALID 6. If the intersection of the premises of an argument is and the conclusion of the argument is regions II, and VII then the argument is VALID INVALID 7. Use a Venn diagram to test the validity of the following argument a + b b For questions 1 - 3, write the set theory counterpart for each logic statement. 1. ~ v b 2. ~(w \~r) 3. ~(~a C) For problems 4 - 6 circle the appropriate word, "valid" or "invalid". 4.
