Show the validity of the following argument ‘If Jemah gets the job and works hard, she will be promoted. If Jemah gets promotion, then she will be happy. She will not be happy. Therefore, either she will not get the job or she will not work hard’.
if you do your homework and get good grades, you'll be happy. But just because you're not happy doesn't mean you didn't do your homework or get good grades. There could be other reasons you're not happy.
