Hello all,

I am trying to prove that the following is true:

<br /> lim_{M \rightarrow \infty} \sum_{P = (\frac{1}{N}-\delta)M}^{(\frac{1}{N}+\delta)M}<br /> \frac{(N-1)^{{M-P}}M!}{P!(M-P)!N^{M}} \rightarrow 1<br />

where P, M, and N are integers, and \delta is an arbitrarily small positive number (less than 1/N).

Any ideas on how I might approach this?

Well, since you're doing statistics, can you interpret that summation as a probability? Maybe you know some things about the probability distribution that might help.
 
Namaste & G'day Postulate: A strongly-knit team wins on average over a less knit one Fundamentals: - Two teams face off with 4 players each - A polo team consists of players that each have assigned to them a measure of their ability (called a "Handicap" - 10 is highest, -2 lowest) I attempted to measure close-knitness of a team in terms of standard deviation (SD) of handicaps of the players. Failure: It turns out that, more often than, a team with a higher SD wins. In my language, that...
Hi all, I've been a roulette player for more than 10 years (although I took time off here and there) and it's only now that I'm trying to understand the physics of the game. Basically my strategy in roulette is to divide the wheel roughly into two halves (let's call them A and B). My theory is that in roulette there will invariably be variance. In other words, if A comes up 5 times in a row, B will be due to come up soon. However I have been proven wrong many times, and I have seen some...
