Question
Determine whether the following argument is valid: She is a Math Major or a Computer Science Major. If she does not know discrete math, she is not a Math Major. If she knows discrete math, she is smart. She is not a Computer Science Major. Therefore, she is smart. 9. Valid ONot Valid Don't know 10. Place the correct symbol from the list C, =, 2 between each pair of sets below a) AU B, AU(B – A) b) AU (BN C), (AUB)NC c) (A – B) U (A – C), A – (BN C) d) (A — С) — (В - С), А — В 11. Suppose f : a) Is f one to one ? [2x – 1]. R → Z where f(x) Yes No Don't know b) Is f onto Z ? Yes No Don't know
