A bit confused with this one: Is the argument correct? if not explain why it's not and change the minor premise to make it correct:
All NBA basketball players are over 5ft. tall
Russell is 6ft tall
Therefore, Russell plays in the NBA
I meant to add my thoughts: I think it is incorrect because of an inverse problem. To make it correct I would write it as:
All NBA basketball players are over 5ft tall
Russell is an NBA player
Therefore, Russell is over 6ft tall.
The first post has made a wrong conclusion. (p->q and q->p are different propositinos)
The second conclusion is correct.
