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. This is the same thing as 1 minus lambda over n to the n times 1 minus lambda over n to the minus k. You have the same base, you could add the exponents and you would get this up here. And let me simplify a little bit more. Let me swap spots with these two.
