我好像把前一篇弄得太枯燥... 来个比较有趣的好了.
如果有个念机率或者念统计的人跟你说...
「机率（统计）这门学问的用途不是在预测未来. 」
那只有两种可能...
第一种是他在骗你, 第二种是他在骗自己.
所以我们还是要回归这门显学的正途: 占卜!

好啦, 其实是怕讲越多错越多............:Q
讲解一下怎麽查表好了...
纵轴局数, 横轴失分.
表里面是「横轴」的「累进机率」, 请不要看错方向.
譬如小王投 7.1 局, 掉 2 分以下的机率是 49.070%.
至於 Halladay 投满七局掉三分以下的机率是 41.685%.
请自行决定你相信哪一格... 就是说, 赌 P 币赌到倾家荡产不要怪我. :D
另外, 如果跟你手上的各家预测不同... 要相信他们. :P
毕竟人家的模型都是七八阶甚至十几阶近似...
而我的懒人模型呢, 只能算第一阶近似.
我发誓绝对不编辑文章............当然, 先发换人的时候例外. :P
PS: 这两篇都是在编辑器里头打好才贴上来, 否则的话表单会出人命.
所以请不要查询本文值几个银币──破产的不负责, 笨死的也不负责.
