From "Oh this has not gone well" (part 14) by Redditor "ThisHasNotGoneWell":
"Well," I started, how do I explain statistics, and not sound like the boringest boring person in the world, "In the world I come from people have enough free time on their hands, and they take games seriously enough, that people will study a game like a Mage might study magic. I had plenty of time when I was waiting for the pass south to clear, so I spent some time pulling the rules apart, figuring out the probability of any given hand. The other players might have a gut feeling as to how probable a given hand is, but I know the figures exactly. I'll also try to keep track of what cards I've seen played already. Between that, and having worked out the probabilities of each, I usually have at least an idea of how good my hand is compared to the others."
"Wait," she said, trying to wrap her head around what I'd just said, "So, you know what cards they have in their hand?"
"Not quite, I know what cards they probably have. And even if I don't know specifics, I'll at least have an idea of whether their hand is better or worse than mine, and that's really all I need."
"Don't humans have anything better to do?"
I thought of the many hundreds of hours spent playing videogames and watching Netflix.
