comment Expectation of a Poisson Process
Yes, like I say above, I'm confused about what to do with this recursive integral. I'm gonna go to bed; need to be up in 3 hours. But I will look at this again tomorrow (or technically later today)

Ok, thanks. Could you take a look at my question? It is somewhat similar to this one, but the approach I took is different. math.stackexchange.com/questions/724228/…

meh, not entirely; it confuses me more I think.

What does $D_i$ represent in therms of the problem? Is it the arrival of car $i$ ?

comment Winning a restricted game of Nim?
Ah...that's what I was missing. I thought we were just xor-ing the size of the piles (which is the Grundy value of the starting positions of each pile anyway). I didn't realize I had to find new Grundy numbers.

Would it remain $n ~mod ~3$ if I were allowed to remove, say, 1 or 3 sticks from each pile (but not 2)?

comment Winning a restricted game of Nim?
ah, ok. I think I get it now. So let me double check. I first perform $(n ~mod ~3)$ where $n$ is the number of sticks in each pile. THEN I take the digital sum on the result?

Ok, but suppose I start with a different set of piles. Say I start with three sticks in pile 2 instead of 4 (and everything else remains the same)? I can't have fractional Grundy numbers.

comment Winning a restricted game of Nim?
ok, so the first pile would become a pile of zero, second and third would become a pile of 1, and the last one would become a pile of 2?

So I would convert my piles to base 3 then? Or take $mod~3$ after taking the digital sum?
