概率归概率。个人觉得按高频看50题就差不多必中啦。

一木菩提UID: 2390164

60会不会保险点....

irvine666UID: 2575525

高频前50我肯定会认真准备，剩下的偶得靠命了...

silverduneUID: 2542879

越多肯定越保险了。。。 不过我是懒人一个，扫了2遍top50，计时写了10个issues。

想想当时确实有点发虚啊，呵呵。 不过我考时2篇都是top50里的。Lucky...

mlwyUID: 2590846

这样看来。。还不如去烧高香~~哈哈，随便说的

comorainUID: 192455

这个概率略有些偏高，因为ETS并非随机抽题，两道题不大可能出同一类型的。

草木也知愁UID: 2487572

这种事不能用概率算滴

变量太多 要建立超过50维的坐标系才行。。。。

以前也有过好几个概率分析
