Question

I need this question completed in 5 minutes with handwritten working

Use the rules of inference to write a proof that the following argument is valid. Write a
justification for each of the steps in your proof. (It is possible to write a proof in seven
lines, but your solution does not need to use this number of lines.)
(P₁ V P2) → (¬P₁) :. ¬P₁

Expert Solution

Step 1: Define the argument.

Consider the given logical argument $left parenthesis space p subscript 1 logical or p subscript 2 space right parenthesis space rightwards arrow left parenthesis not p subscript 1 right parenthesis$ $therefore space not p subscript 1$

To prove that the given logical argument is valid, it suffices to show that the truth table of

$left parenthesis p subscript 1 space logical or space p subscript 2 space right parenthesis space rightwards arrow left parenthesis not p subscript 1 right parenthesis space space a n d space not p subscript 1$ has same values.
