VoyForums Announcement: Programming and providing support for this service has been a labor of love since 1997. We are one of the few services online who values our users' privacy, and have never sold your information. We have even fought hard to defend your privacy in legal cases; however, we've done it with almost no financial support -- paying out of pocket to continue providing the service. Due to the issues imposed on us by advertisers, we also stopped hosting most ads on the forums many years ago. We hope you appreciate our efforts.

Re: 理論基礎

你說兩粒骰子連續三次擲到12 的機會
正確是 1/36 x 1/36 x 1/36

你妹妹說 1 - 35/36 x 35/36 x 35/36 是不對的,因為她的計法,是計出三次中 每是非擲到12 的機會,意思即是三次中 "擲到一次12 點" 或 "擲到兩次12 點" 或 "擲到三次12 點" 的機會
