Suppose that P(n), Q(n) and R(n) are statements about the integer n. Let S(n) be the statement: "If P(n) and Q(n) are both true then R(n) is true." (a) The contrapositive of S(n) is the statement If R(n) is true then P(n) and Q(n) are both true. If R(n) is true then at least one of P(n) and Q(n) is false. If R(n) is false then P(n) and Q(n) are both false. If R(n) is false then at least one of P(n) and Q(n) is false. If R(n) is false then P(n) and Q(n) are both true. If at least one of P(n) and Q(n) is false then R(n) is false. If R(n) is true then P(n) and Q(n) are both false. None of the other answers. (b) The statement: "If R(n) is true then P(n) and Q(n) are both false." is The converse of S(n). The contrapositive of S(n). The converse of the contrapositive of S(n). None of the other answers. (c) You want to prove that S(n) is true for all n EN via the contrapositive. Your proof should start by assuming that n E Nand P(n) and Q(n) are both true. P(n) and Q(n) are both false. R(n) is true. R(n) is false. At least one of P(n) and Q(n) is false. At least one of P(n) and Q(n) is true.
