Consider the statement: For any numbers a and b, if a + b is odd, then either a or b is odd. First, give a valid proof of the statement using proof by contrapositive. Drag 3 of the statements below to the right column. Statements to choose from: Your Proof: Put chosen statements in order in this column. Therefore a + b is even. Let a and b be integers and assume both are even. Let a and b be integers and assume that a + b is odd but a and b are both even. But then a + b is both even and odd, a contradiction. The sum of two even integers must also be even. Let a and b be integers and assume that if a + b is odd, then either a or bis odd. Let a and b be integers and assume a + b is odd.
