Question

If p and q are simple propositions, then p left right double arrow tilde q is true when

  1. p is true and q is true    
  2. Both p and q are false    
  3. p is false and q is true    
  4. None of these    

The correct answer is: p is false and q is true


    p left right double arrow   tilde q is true iff p, ~q are both true or both false.
