<p>I'd say that <em>some</em> sports betting questions could find a home on CV, but not enough to not justify their own site. To use an example that's actually an official SE site: <a href="http://rpg.stackexchange.com">http://rpg.stackexchange.com</a> has some potential questions that are probabilistic - what's the distribution of values from a particularly opaque dice-rolling system, or particular optimizations (a sword with a higher mean value versus one with a lower mean but a narrower variance in terms of damage).</p>

<p>But its faster, and likely more productive, to ask someone who is already up on the longsword vs. greatsword debate.</p>

<p>This is true for sports betting as well - you could ask many of those questions here, but a huge amount of time would be spent on "defining your terms" in a way that wouldn't be required with field specific expertise. There are occasionally sports-related questions that are on here, but I don't think there will ever be a sufficient concentration of them to satisfy the sports-betting enthusiast. And if the questioner <em>can't</em> properly define their terms and lay out the problem in a generalizable form, they're well and truly out of luck.</p>
