Ya, well thats an educated guess. A (guess) itself has more then just that definition. If I diden't have any information, such as,
If you said to me, "Which direction will the wind blow if your standing on a rock in florida on Beech street 35 years from now and will there be a girl standing on a roof cleaning a chimney?", And you only know the facts. I could answer to you and say, "Well, knowing that I know about direction and that the wind can only blow in one direction, I than can make an educated guess. I would say north.
And If I can't make an educated guess, weather there will be a girl on a roof cleaning a chimney, and you asked me to guess. I can eather say yes or no.
