I get it now. Thanks! Put all that into an answer and I'll accept it.

comment Calculating odds of a dependent series
I see, I think. All the other threes have P(1/4)*P(1/2), but MM flows to a P(1/4)*P(0) and a P(1/4)*P(1) instead. Right?

@user130512 - Why don't they? Does MMH count double because MMM isn't valid? That would seem to be the reasoning from #2, but I don't understand why.

comment How to prove that a $3\times 3$ Magic Square must have $5$ in its middle cell?
It's also worth pointing out that this question only applies to normal magic squares (i.e. 1...n). The general magic square might not have a 5 in it at all, let alone in the center.

comment Optimizing response times of an ambulance corp: short-term versus average
I like this approach, because it's relatively simple. Obviously, you'd have to define what "poor" coverage is sufficiently rigorously to make this practical to apply, but simulations based on real-life data should help pin that down.

comment What's the probability that Abe will win the dice game?
@Joren - I've done it both ways. The problem with the d6 is sometimes you forget to declare whether you're mapping it that way, or whether you're mapping it 4->1, 5->2, 6->3. Which is also perfectly valid. With the d4, there's no question about it. Admittedly, it may not have been the best choice of examples.

As a visitor from rpg.stackexchange.com, I can say that it's very common to generate dice which you don't have (such as a d3) by saying "Roll a d4 and reroll 4's". Effectively, any result you reroll from scratch doesn't exist on the die. I wouldn't have been able to state it formally, though, which is why I'm just a visitor here!
