Well, we have a total of n moments, and k of them were successes. So we'll have n minus k failures. Let's see what we can do with this. So this is equal to, let me rewrite it all, and I'll change colors. The limit as n approaches infinity. Let me write out this binomial coefficient. That's n factorial over n minus k factorial times k factorial, normally I write these the other way around, but it's the same thing, times, let's see, lambda to the k, I'm just using my exponent properties, over n to the k. And then this expression right here, I can actually separate out the exponents.
