Are the winners picked randomly from all entrants who correctly answer and submit all required information? I'm not planning to enter, but I figured I'd be the first to ask this in case anyone else might also wonder.
More than likely when I go through all of the submissions that have correct answers they will be selected at random, yes. I took a page from the contest Jon set up in this format - lots of kids entered, but he did first come, first serve and a lot of the later entering kids didn't have a chance. (Especially due to some of the winners submitting entries 5 or 6 times under different emails, hence our 1 entry per person rule and why we ask for so much information.)
