I too agree that the P NP has the best chance of being solved by someone from FIRST. If you looked at the pdf descriptions of the others, most involved incredibly complex equations of which they want proof. Also, you must keep in mind that some people have dedicated their whole lives to solving these questions--not to discourage anybody, though. I believe these others would just be too advanced for most people. Even FIRST people.
I'd love for someone to prove me horribly wrong by solving all of them. (Or even one

)
