Let R be a relation on the set of all integers such that aRb if and only if a + b is even. To show that R is anti-symmetric, we must prove that For any integers a and b, if a ‡b, then a + b is even and b + a is even For any integers a and b, if a ‡b, then a + b is odd and b + a is odd For any integers a and b, if a + b is even, then b + a is even ● For any integers a and b, if a ‡ b, then a + b is odd or b + a is odd For any integers a and b, if a ‡ b, then a + b is even or b + a is even To show that R is not anti-symmetric, we must find a counterexample satisfies which of the following statement? O For some integers a and b, a ‡ b and a + b is odd and b + a is odd For some integers a and b, a ‡b and a + b is even and b + a is even For some integers a and b, a ‡ b and a + b is even or b + a is even For some integers a and b, a + b is even and b + a is odd O For some integers a and b, ab and a + b is odd or b + a is odd

Let R be a relation of the set of all integers such that aRb if and only if a + b is even. 

 

Let R be a relation on the set of all integers such that aRb if and only if a + b is even. To show that R is anti-symmetric, we must prove that For any integers a and b, if a ‡ b, then a + b is even and b + a is even For any integers a and b, if a ‡ b, then a + b is odd and b + a is odd For any integers a and b, if a + b is even, then b + a is even For any integers a and b, if a ‡b, then a + b is odd or b + a is odd For any integers a and b, if a ‡ b, then a + b is even or b + a is even To show that R is not anti-symmetric, we must find a counterexample satisfies which of the following statement? For some integers a and b, a ‡ b and a + b is odd and b + a is odd For some integers a and b, a ‡b and a + b is even and b + a is even For some integers a and b, a ‡ b and a + b is even or b + a is even For some integers a and b, a + b is even and b + a is odd O For some integers a and b, a ‡ b and a + b is odd or b + a is odd
