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

Thanks!

    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.
