4) Determine the validity of each argument. a) If Mary is wearing green socks, she has passed algebra. But Mary is wearing blue socks. Unfortunately, she must have failed algebra. b) Determine whether the argument is valid. If 8 is even, then 4 does not divide 5. Either 7 is not prime or 4 divides 5. But 7 is prime. Therefore 8 is odd (not even).
