P only if Q….

Hi everyone,

I’m writing to follow up on a discussion we had in class today, regarding methods for translating conditional (“if…then”) statements from English to symbols.

We started with:

If it rained, the ground got wet.

Which we symbolized as

R -> W

Where R = “it rained” and W = “the ground got wet”.

We then got stuck on the phrase:

It rained only if the ground got wet.

The correct symbolic version of this is:

R -> W

just as it appeared in the slides, where R = “it rained” and W = “the ground got wet”, just as before.  This is counterintuitive, but true!

For a longer discussion, with some better examples, take a look at this page (otherwise, just memorize it!):

Assignment.  To get started , you must complete the following three steps.

Step 1.  Log in to WeBWorK here:  I have created Usernames and Passwords for each student registered for my class.

Username.  Your username for WeBWorK consists of your first initial plus your last name, all lowercase (for example, John Smith would have username ‘jsmith’).
