Hi Stephen,
Sorry, so for b) it is only asking for the instance where both If P then Q and Not (Q or P) are false or a case when both are true (logically equivalent?)? Is it simply just asking me to substitue sentences for an instance where both P and Q are false?
1= true
0= false
P Q...
Hi Stephen,
Thanks again. So for part b) I still cannot think of anything in regard to your new insight.
For example;
P: 2 + 2 = 4
Q: I am a pig

Been at this all day and cannot come up with an instance where in english sentences, If P then Q is equivalent to It is not the case that P or Q. Can anyone provides some hints.. I am really stuck. Thanks!
