Define converse and contrapositive.

Answer»

Converse and contra positive are certain other statements which can be formed from a given statement with ‘if then’. 

  • Converse: The converse of the statement if p, then q is defined as ‘if q then p’. i.e., the converse of a implication p ⇒ q is q ⇒ q 
  • Contrapositive: The contrapositive of the statement if p, then q is defined as ‘if ~q, then ~p’ i.e., the contrapositive of a implication p ⇒ q is ~q ⇒ ~p 

Note: 

Inverse of a implication p ⇒ q is ~p ⇒ ~q
