True Or False: P->(QVR) equivalent to Pn~Q -> R Notes from Student: For P->(QvR) equivalent to Pn~Q -> R: I'm still very confused I'm told it is false but odn't understand why... P->(QvR) equivalent to Pn~Q -> R: Using logic of P->Q and ~PvQ wouldn't it be true to say that ~PvQvR you would then have... ~(~PvQ)->R which becomes Pn~Q-> How is that not true in this case of the two statements being equivalent?
