Given the true statements "if students are in grade 9, they take gym." Which statement is logically correct?
1. Bo is taking gym; therefore, she is in grade 9
2. Maria is not in grade 9; therefore, she is not taking gym.
3. Ed is not taking gym; therfore, he is taking Health.
4. Steve is not taking gym; therfore, he is not in grade 9.
I dont understand this. I used the p and q, and tried to use the "conditional" way, like if p then q. THen i used the inverse, which would give me 2. Would that be correct? If it's wrong tell me how i am wrong. =/
