7/10上海北回来放狗

蜗牛在家喊加油

作文：感谢CD Self-employment那篇写的十分顺手，详细的JJ有了，不多叙述

IR：

这道IR是一出来就是这么多色子，实在难忘。原谅我实在忘记了画图的规律，但是肯定，这个题目有规律性的画出每个色子的点数。
题目有两个问题需要回答。
1. 两个色字相加和为8的几率是多少，我仔细看了，也就我画红线的那一斜列和为8，所以答案是1/9。
2. 两个色字相加和为8，至少有一个色子是2的几率是多少，这个我不确定我对不对，有人可以解答的话，自己补充吧。

逻辑：我只想起来两只，而且题目曾经做过的。是两道原题，一点都没有变化。
1. Nitrigen dioxide is a pollutant emitted by automobiles. Catalytic converters, devices designed to reduce nitrogen dioxide emissions, have been required in all new cars in Donia since 1993, and as a result, nitrogen dioxide emissions have been significantly reduced throughout most of the country. Yet although the proportion of new cars in Donia's capital city has always been comparatively high, nitrogen dioxide emissions there have showed only an insignificant decline since 1993.

which of the following, if true, most helps to explain the insignificant decline in nitrogen dioxide emissions in Donia;s capital city?
A more of the cars in Donia's capital city were made before 1993 than after 1993.
B the number of new cars sold per year in Donia has declined slightly since 1993
C pollutions other than nitrogen dioxide that are emitted by automobiles have also been significantly reduced in Donia since 1993
D many Donians who own cars made before 1993 have had catalytic converters installed in their cars
E most car trips in Donia's capital city are too short fro the catalytic converter to reach its effective working temperature.

E是答案

2。 这题是关于车子容易被树枝砸，冬天下雪，说雪很重容易压断树枝，车容易被砸到。而秋天的话反而比冬天更加容易被断掉的树枝砸。原题暂时找不出来，但是我觉得很多人应该会有印象。答案是秋天的风比较大，所以容易被砸到

阅读：感谢CD 考的四篇分别是marble雕像，火灾，企业外包，还有超市选择/促销。

Thanks for sharing!!!

谢谢楼主的热情分享！

但是有个小问题- IR 第一题 我觉得应该是5/36吧？因为情况有：2+6, 3+5, 4+4, 5+3, 6+2
第二题 2/5 [（2+6和6+2)/5种和为8的情况]

不知对不对^^

因为图具体规律我忘记了，所以一下子也说不上来，但是我红线画出的那一列肯定是正确的，其他列或行我都没找出相加为8的，所以我选择的是1/9，总之这道题不算难，但是我没来得及好好算，不过按你的说法，你这样算是对的呢
