LZ使这个么？

Principle of Reciprocal Demand 

• That is to say the two participants of trade in Recardian model must establish a specific relationship with each other, this is the reciprocal demand relationship.
• It is this reciprocal demand that actually determines the prevailing terms of trade and how much gains obtained by a particular country.
• In other words John Stuart Mill had resolved the problem of how to exactly reach the rate of exchange in international market. Comparative advantage and law of reciprocal demand due to John Stuart Mill constitute the two basic building blocks of the classical theory of international trade.

就是这个单词，而且我很肯定文章里面用的是： norm  of reciprocal

I think it should be 4/90 = 2/45. (not sure whether my logic is right.)

take two out of the box, one after another, so it should be P(10)2 = 90

1+2, 2+1, 1+3 and 3+1 are less than 5, so 4/90 = 2/45

What do you think?

哈哈~~doctortt 跟我一开始犯了同一个错误~答案里面是没有2/45的~

因为平均数是5.5， 所以应该是

1+2，2+1，1+3，3+1，2+3，3+2，1+4，4+1  so 8/90=4/45
