So naturally I took it as a challenge to find the typo. While I was searching, I enjoyed the book very much. If you are interested in etymology, linguistics, and history, I recommend it!<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As it turned out, I found exactly one typo. When I told Michelle, she asked me nervously which page it was on. Page 17. She looked disappointed \u2013 that was not the same typo she found.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Now, for people who like Bayesian statistics, this scenario raises some questions:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>After our conversation, how many additional typos should we expect there to be?<\/li>\n\n\n\n<li>If she and I had found the same typo, instead of different ones, how many typos would we expect?<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">As it happens, I used a similar scenario as <a href=\"https:\/\/allendowney.github.io\/ThinkBayes2\/chap15.html#the-lincoln-index-problem\">an example in <em>Think Bayes<\/em><\/a>. So I was able to reuse some code and answer these questions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/allendowney.github.io\/ThinkBayes2\/ok.html\">You can read my solution here.<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/colab.research.google.com\/github\/AllenDowney\/ThinkBayes2\/blob\/master\/examples\/ok.ipynb\">You can also click here to run the notebook with the solution on Colab<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>When I started work at Brilliant a couple of weeks ago, I learned that one of my new colleagues, Michelle McSweeney, just published a book called OK, which is all about the word OK.
