WebA proofis an argument from hypotheses(assumptions) to a conclusion. Each step of the argument follows the laws of logic. a statement is not accepted as valid or correct unless it is accompanied by a proof. This insistence on proof is one of the things that sets mathematics apart from other subjects. WebOur conditional statement is: if a population consists of 50% men then 50% of the population must be women. p → q If we exchange the position of the hypothesis and the conclusion we get a converse statemen t: if a population consists of 50% women then 50% of the population must be men. q → p
