Well, I just don't like doing pointless busywork (I get enough of that at school). I prefer logic-based puzzles and mysteries, something that involved creative and lateral thinking usually. I know your a huge math buff but you have a passion I just don't share.

Frictional

90% of applicants to Frictional Games are Swedish. 78% of the Swedish applicants have degrees in computer science, while 65% of non-Swedish applicants have a degree in computer science. Anyone with a degree in computer science has a 33% chance of getting into the company, while those who do not only have a 17% chance. Find the probability that a successful applicant is not Swedish.
