I'm not sure why it's relevant that they're 16-year-olds, and that prompts me to consider that this is really a question for teachers about pedagogy rather than for mathematicians about mathematics, so this may not be the right place to ask. I've raised the scope question [on meta](https://math.codid... (more) |

Question | — |
Is mathematical pedagogy in scope? Do we want to consider questions about how to teach mathematics in scope, or do we want to restrict questions to actually doing mathematics? (more) |

Firstly, it wasn't my edit. I don't understand why you call it my edit after having described the situation accurately in the question. Secondly, I understood the question to be about the edit summary. If that wasn't the main point, I suggest either editing the question or asking a new one. Thirdly, ... (more) |

The question "But why do most answers on lotteries consider the Pr(winning jackpot in 1 play)" might be on-topic as a *meta* question, but the answer is going to be along the lines of "Because that's what the questions ask about". As to *Homo economicus*, this is a mathematics site, and while tightly... (more) |

Answer | — |
A: Should posting on Meta affect reputation? It seems like a good thing to reward useful contributions to Meta, but probably not as much as useful contributions to Q&A. I have mixed feelings about negative scores for downvotes, but bearing in mind the use of downvotes to express disagreement with good-faith proposals I'm inclined to remove them... (more) |

Comment | Post #288022 |
It's not impossible in principle to make a profit by buying every number combination, although it requires a large syndicate both to invest and to obtain the tickets; a lottery where unwon prizes roll over so that the jackpot gets large enough to be worth it; and a bit of luck so that you're not shar...

I was specifically assuming that the numbers on each ticket are *not* randomly generated but chosen by the player. (more) |

Comment | Post #287999 |
I would say that in the context of the question the chance of winning is linear with the number of tickets because we can assume that the tickets will not have the same numbers, and a perfect match with the selected numbers is required to win, so they cover different outcomes of a single event.

To properly answer this question we would need full details on the prize structure (because most lotteries have more than just the top prize) and sufficient details on the ticket structure to estimate the chances of prizes being shared. (more) |

I think that it's intended to be seen as community reputation rather than mathematics reputation: it measures your contribution to the math.codidact.com community (and that, in turn, is arguably a proxy for activity in the math.codidact.com community, as long as you're not mainly making posts which g...
