Question 191999
# 1 I'll do the first part a) to get you started.


Conditional statements are of the form "If P, then Q" where P is the antecendent and Q is the consequent.


So 


Antecedent: I go to work
Consequent: I will get paid




The converse of "If P, then Q" is "If Q, then P". So the converse of "If I go to work, then I will get paid." is "If I get paid, then I will go to work"


----------------------------------


The inverse of "If P, then Q" is "If NOT P, then NOT Q". So the inverse of "If I go to work, then I will get paid." is "If I do NOT go to work, then I will NOT get paid"



-------------------------------


Finally, the contrapositive of "If P, then Q" is "If NOT Q, then NOT P". 


So the contrapositive of "If I go to work, then I will get paid." is "If I do NOT get paid, then I will NOT go to work."



Note: the "not"s are capitalized for emphasis and you obviously wouldn't write them out like that.

Q: Rewrite ~ (p  ~q) using DeMorgan's laws. 


What is the question mark for? Does a symbol go there?
