Question

Use a truth table to

determine whether the following argument is valid or invalid.
p ∨ q
p → r
q → r
... r

Answer 1

The argument in question is a disjunctive syllogism, which is a valid deductive inference. By using a truth table, we can determine whether the argument is valid or invalid. In this case, the argument is valid.

Step-by-step explanation:

The argument in question is a disjunctive syllogism, which is a valid deductive inference. In this argument form, if one of the two statements joined by 'or' is false, then the other statement must be true. By using a truth table, we can determine whether the argument is valid or invalid. In this case, the argument is valid because the truth table shows that whenever the premises are true, the conclusion is also true.
