How many rows are in a truth table?

A logical statement having ncomponent statements will have 2nrows in its truth table. Number of Rows in a Truth Table ?2012 Pearson Education, Inc.Slide 3-2-16 After making several truth tables, some people prefer a shortcut method where not every step is written out. Alternative Method for Constructing Truth Tables 9/11/2013 9

What is a valid argument if the truth table is always true?

Since the truth table for [ ( B ? S) ? B] ? S is always true, this is a valid argument. Create a conditional statement, joining all the premises with and to form the antecedent, and using the conclusion as the consequent. Create a truth table for that statement. If it is always true, then the argument is valid.

Is it possible to construct a truth table for two variables?

input variables, not two. Therefore, one cannot use the truth table format given above. Fortunately, it is still very easy to construct truth tables for three or more variables.

How do I change the truth table entries?

To change the truth table entries, all you need do is click on the square associated with the truth table value you want to change. Clicking on one of these boxes toggles (inverts) that value in that square. For example, try clicking on the DCBA square several times and observe the results.
