$title = "Conditional"; //
The truth table for P or Q is as follows:
If you have Java, try it out for yourself:
Set the truth values for the propositions P and Q by clicking on the appropriate button beside "P" and "Q" respectively. What is the truth value of If P then Q? Find out by clicking on the "Compute" button.
A special conditional occurs if we flip the P and Q around: we get if Q then P, which is the same as saying P only if Q.What is the truth value of P only if Q? Find out by clicking on the "Compute" button.
Notice that P only if Q is false only when Q is true and P is false.17 August 1996 include "footer.inc"; ?>
