Over in another meta thread, there is a conversation about a particular question regarding dice-rolling outside of an RPG context. I suggest you read that thread first, but to boil it down to the basic points: RPG.SE is probably the best place we know of to get an answer for that sort of question, but outside of an RPG context such a question is probably off-topic.
One point that I haven't seen any significant disagreement on (and which I agree with myself) is that if a person wants to roll some dice and get a number with a particular statistical distribution with a minimum of fuss, there's probably no better place on the internet to ask about it than here.
Given that, should we explicitly expand our site's scope to include questions that are about rolling dice, regardless of an RPG context?
A good Yes answer should probably include information and guidance on how to determine if a particular Dice question is a good question. A good No answer should show why expanding our site's scope this way would be harmful to the site.
This question is generally unconcerned with the outcome of the linked meta question. Whether all dice questions are implicitly part of our purview or not doesn't change whether or not they should be included explicitly.
