Question 192750
<pre>
The only thing promised in this condition statement is that if it is raining then we will close the window
:
just because we close the window doesnt necessarily mean it is raining. It might or might not be raining
:
basically if p is the statement it is raining and q is we will close the window
:
We are given... if p then q or p->q. We are asked does q -> p

truth table
:
p  q  (p->q) -> (q->p)
