4/6 is the same as 4-6, there are many ways of displaying odds. Here the 4/6 actualy resolves the odds. Something you need to consider in the Kata. The 20% is the 'bookmakers margin', I thin the description explains what that is. But do you think more clarity is needed?

Hey, I made an alteration to the random tests and used you're solution - seems to be working OK. Test.assertEquals - > Test.assertSimilar

Yeah.. :( just after I published this one, I saw that as a beta. What do I do? attempt to alter it? In fairness I've just checked that one out and seems its missing some essential testing. I've also got 2 follow up Katas in the making

How does the kata look? I value you're opinion :) annoyingly just after publishing I've just seen there is another beta kata quite similar... but only 14 solves and a few issues.

Hey Giacomo! I'm not sure if some of the issues above relate to ruby/python, but I'm not experienced enough either with those languages to resolve them - think you could check it out? Thanks!!

Thanks for pointing this, which language is the issue in?

Thanks for testing, I believe I've fixed the random cases and expanded the blacklist! Hope its functioning as intended now.

You're correct, I've spent some time checking my solution and believe I've found the issue. Would be great to see if its working for you. Hoping to resolve the random test issue! Thanks again for testing

Thanks, I've made a more inclusive blacklist

Think exponential decay (use the link provided to get some info on it)

what language?

The system is clearly alcoholic! :)... That is very very odd, I've just checked and I wasn't getting that problem. Have you ran a few times? I guess there is a 2/7 chance we'll see beer or wine for each item.

Your decay isn't quite right. You've made "motivation" = 100month0.15. You need to think about exponentials!
