Girl graduated from university on 9 1 and went to teach in Lijiang, Yunnan, with a woman and two men beside her. After teaching, I hitchhiked to Tibet for a week. Weibo

It is difficult to judge the probability, which depends on the following factors:

Face value of men and women

Family conditions of four people

The future development direction of the four people.

Did four people break up without graduating from college?

Are there any photos of them making out with the opposite sex (mainly women) in their respective Weibo or circle of friends?

Focus on the first and fifth items: if there is too much difference between two faces, it is basically impossible. If the two faces are similar, the performance may be around 70%. Furthermore, if a girl posts a personal photo of another person in her personal circle of friends or Weibo, the probability is 80%.

Of course, "bus" and "kaleidoscope" do not belong to the category of probability.
