I'm sorry John. I did not mean the "REAL" person solving this problem when I said basic intellegence is assumed. I meant that it is assumed that the four boys in the problem have basic intelligence. That is how "Travis" is able to know is has a black hat on (since Larry dosen't say anything). I was not commenting on you -- far from it. If I had more 'basic intellegence' maybe I would know how to express myself better.
