Dan and Lisa's answers agree on all but problems 6 and 9, and Dan got two more correct than Lisa. So Dan is correct on both 6 and 9. Therefore, Mary is incorrect on 6 and 9. So she got seven of the other eight correct, and Dan got three of the other eight correct. But on those eight problems, Mary and Dan disagree on only problems 2, 3, 5, and 10, therefore Mary got all four of those correct. Then Mary got three of problems 1, 4, 7, 8 correct, but everyone answered the same way on those, so Colin got three right on those problems as well. Then read off the deduced answer key for the other six problems to get Colin's final score.

Your body actually produces a small amount of cyanide endogenously, if it makes you feel any better. It has some role in cell signalling.

I feel like https://xkcd.com/221/ might be heavily influencing what the typical "random" die roll looks like on the internet ;)

The thing you're missing is that at no point is it assumed that there are exactly two elements in a boolean algebra. In fact you can have a boolean algebra with four elements (see https://en.wikipedia.org/wiki/Boolean_algebra_(structure)).

Wizards of the Coast's in-house card database (Gatherer) is basically not maintained at all. I think they're very happy there is a third party willing to do that for free, and for a game with as much history as Magic, having a searchable card database is basically mandatory.

It is not. a and b are not symmetric in this equation, you can't just swap them.

This is covered by the article. A board game might take 4 people and 2 hours to play. If your three friends didn't have fun with a board game the first time, they probably won't want to play again, and so you won't be able to play again either. Therefore there is a strong drive among boardgamers to play the "full" game the first time, because there might not be a second time.

It also adds extra difficulty to design a game that even has a simple version that is fun to play. Take your Texas Hold'em example, imagine it takes 2 hours to play one game. If you start with a version that has all cards face-up and no betting, people would conclude that Texas Hold'em is a supremely boring game, and wouldn't bother to try the full Texas Hold'em experience!

An American's life expectancy when they're born is around 76. But the life expectancy among Americans that have already lived to the age of 65 is more like 83.

The conjecture is true for all small graphs that they tried, so if it's "obviously" false to you then something went wrong with your intuition somewhere.

For air transport in the U.S., it's not just one certificate, it's many. You get your private license, instrument rating, multi-engine rating, commercial certificate, instructor certificate, and finally the air transport certificate. And you're not allowed to even think about that last step until you've accumulated 1500 flight hours on the previous steps. Being allowed to write a Javascript login page is easy pickings compared to that.
