条件概率

条件概率公式：
P(A|B) = P(AB)/P(B)
P(AB) = P(A)P(B|A) ＝ P(B)P(A|B)
P(A|B) = P(A)P(B|A)/P(B)
全概率公式：
P(A) = P(B1)P(A|B1) + P(B2)P(A|B2) + ... // B1,B2...是全集

Here are some things you can do with Gists in GistBox.
// Use Gists to store code you would like to remember later on
console.log(window); // log the "window" object to the console

程序员必读书单－VCS

VCS看起来在“专业的软件开发素养”这个分类中。

VCS

VCS是软件开发生命线。首选git，让开发者主动感知仓库管理，生命周期才完整灵动。

所有不以VCS为一等公民的软件流程都是耍流氓！都会被遗忘而僵死！

使用VCS管理代码、发布/版本管理，在VCS上工作流展开有效的项目流程管理和高效的开发协同。
