Hi, I have two questions which might have one simple answer.
Can someone please explain to me why I shouldn't do a biconditional every time it says if m, not k (m --> /k). I mean the contrapositive would be if k, not m (k --> /m). So why not write it as m (---) /k ?
How does biconditional affect the rule of "if Sufficient condition not satisfied rule goes away and if necessary condition satisfied rule goes away"? when there is "m (---) /k" and the question says "not k" then the rule goes away?
