Actually I should have used the implementation that can be found here on RC! but I rolled my own before looking. --[[User:Walterpachl\|Walterpachl]] ([[User talk:Walterpachl\|talk]]) 18:57, 22 January 2015 (UTC) == Possible extension? == Nice task. While implementing it, I found myself briefly misunderstanding the "draw" scenario and an interesting alternative occurred to me. What if a "draw" resulted in the game being re-run? This changes the probabilities fairly significantly (not just <tt>W/(W+L)</tt>, but <tt>(W + D*k)/(W+L+D)</tt> for some <tt>k</tt>, which can be determined by running lots of trials or by calculus. That probably puts it more in the realm of a Project Euler task than RosettaCode, but might make a fun extension. --[[User:Aspectcl\|Aspectcl]] ([[User talk:Aspectcl\|talk]]) 04:50, 20 June 2015 (UTC)
