    Why literally every kata about bookmaker always has inadequate explanation about the whole subject?

    I would like to know, in your example of the description, how to calculate 20% ?

    • myjinxin2015 Avatar

      And I don't know why its [4/6, 6/4, 4/1] instead of ['4-6', '6-4', '4-1']?

      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?
