## Truth Table for Affirming the Consequent

August 12, 2011 No CommentsA simple interactive truth table for proving the validity of Affirming the Consequent

Click ‘start’ to begin. Then click on the ‘P’ and ‘Q’ on the left to drag the truth-values to the atomic components of the sentences. You’ll see a T/F appear under each connective. Set the correct values and click on ‘Check’ to verify. When the table is completed, it will prompt you to highlight any rows with a false conclusion, and then circle the truth-values of the premises to verify if they are both true. If there are no rows with true premises and a false conclusion, it’s valid (by definition).
