Propositional and First Order Logic.

The formulas of propositional logic below implicitly assume the binding priorities of the logical connectives put forward in Convention 1.3. Make sure that you fully understand those conventions by reinserting as many brackets as possible. For example, given p ∧q →r, change it to (p ∧q) →r since ∧binds more tightly than →. (a) p ∧q →r (b) (p →q) ∧(r ∨p →q) (c) (p →q) →(r →s ∨t) (d) p ∨(q →p ∧r) (e) p ∨q →p ∧r (f) p ∨p →q (g) Why is the expression p ∨q ∧r problematic? | Numerade

Write the argument using propositional wffs (use the statement letters shown). Then, using propositional logic, including the rules in Table 1.14, prove that the argument is valid. Either Emily was not home or if Pat did not leave the tomatoes, then Sophie was ill. Also, if Emily was not home, then Olivia left the peppers. But it is not true that either Sophie was ill or Olivia left the peppers. Therefore, Pat left the tomatoes and Olivia did not leave the peppers. E, P, S, O | Numerade
