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. The image presents a logical argument in symbolic form:(c) 1. \((p \land q) \rightarrow r\) 2. \(\lnot r\) 3. \(q\) ∴ \(\lnot p\)This structure is an example of a logical deduction, possibly demonstrating a type of logical reasoning, such as modus tollens, within a formal system. The argument suggests that if both \(p\) and \(q\) together imply \(r\), and \(r\) is not true, then \(p\) must also not be true given that \(q\) is true.

Question

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.

The image presents a logical argument in symbolic form:

(c)
1. \((p \land q) \rightarrow r\)
2. \(\lnot r\)
3. \(q\)
∴ \(\lnot p\)

This structure is an example of a logical deduction, possibly demonstrating a type of logical reasoning, such as modus tollens, within a formal system. The argument suggests that if both \(p\) and \(q\) together imply \(r\), and \(r\) is not true, then \(p\) must also not be true given that \(q\) is true.
