-Use the rules of inference and the laws of propositional logic to prove that each argument is valid. Number each line of your argument and label each line of your proof "Hypothesis" or with the name of the rule of inference used at that line. If a rule of inference is used, then include the numbers of the previous lines to which the rule is applied. For the arguments stated in English, transform them into propositional logic first. a) (10...

Write the argument using propositional wffs (use the statement letters shown). Then, using propositional logic 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

Logic. [3 marks
ii. Suppose you use resolution to prove that KB = a. Does this
mean that a is valid? And why? [3 marks

Prove the following sentence is valid, unsatisfiable or satisfiable by applying a sequence of logical inference procedures, not by truth table enumeration. (I pass Math265 and I do not make an A) and (If I pass Math 374 then I make an A) First, convert the sentence in the Propositional Logical sentence by defining the propositional symbols and connectives; then, prove it.

Directions. Determine whether the following three arguments are valid using the truth table method. Use the Indirect Truth Table method as found in the link on Canvas. Indicate whether each is valid or not. Note that ‘//’ is used as the conclusion indicator and ‘/’ is used to separate the premises. [Note: Use only the following logical symbols: ‘&’ for conjunctions, ‘v’ for disjunctions, ‘->’ for conditionals, ‘<->’ for biconditionals, ‘~’ for negations.] Show your truth tables. 1. (S <->...
