Hello, I'm David Eppstein. I wanted to let you know that one or more of your recent contributions to Probability theory: has been undone because it did not appear constructive. If you would like to experiment, please use the sandbox. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. —David Eppstein (talk) 14:31, 13 January 2016 (UTC)
