| Sep 20, 2016 at 13:31 | comment | added | GeoMatt22 | It has been a while since I was a math major, so I apologize if my answer lacked rigor. (Just please don't tell me it relies on the axiom of choice, as that would be humiliating!) :) | |

That doesn't mean you should go to every other answer and say that yours is so much better. They're all fine as well. Not everything has to be approached in the most abstract and general way possible. | |
| Aug 30, 2016 at 9:50 | comment | added | Meni Rosenfeld | @William, I don't think your comment is appropriate for several reasons. 1. I never said that you need geometric series for this. 2. The concepts you use in your answer are much heavier machinery, it's ironic to say "you don't need geometric series! You just need the much more advanced and sophisticated strong Markov property". 3. A solution which is simple and rigorous was already provided by dsaxton. Your method is more roundabout and overkill for this problem. 4. The OP already had an expression equivalent to a geometric series, someone had to address that, may as well be me. | |
