Grab 0.01 may not point back north found WeChat red were not randomly assigned to Wen Liqin you may have encountered such a situation, the boss put you and Zhang into a mass of red envelopes to relax, the WeChat value of 200 yuan, your eye, before opening, a look: fall! 0.01 yuan! Xiao Zhang ha ha led to the rest of the red envelope. Although the 200 yuan cast in the way you are not necessarily echocardiography (just under the assumption of normal people may still be picked up), but this is at least 200 yuan, the boss will grab 0.01 yuan is not a little upset? It’s not your bad luck. Recently, the Peking University teachers and students through the study found that the amount of red envelopes grab WeChat may not be randomly assigned, and the user registration time has some relevance. The results of the study by the Peking University Institute of undergraduate student Li Xingyu in the WeChat public number "thinking iThink" published. The WeChat red doubts whether random distribution is created by Peking University – Princeton University "Chinese contemporary society" seminar of 12 university undergraduate students and 15 undergraduate students in Princeton University. After school, Professor of Princeton University, the American Academy of Sciences, the teacher Xie Yu will be invited from time to time a student lunch. This invitation is very interesting, that is, in the course of the group issued a number of red envelopes (more than the number of courses), students voluntarily receive, the highest amount of money with the teacher lunch. The red envelopes activities carried out several times, there was an interesting phenomenon: received the highest amount of the vast majority are university students; in addition, only two Princeton University students received the highest amount of these two points is a registered WeChat account of the time earlier. In response to this phenomenon, Professor Xie Yu put forward a conjecture: the amount of red packets received by participants may not be completely random, but with the user experience (registered account sooner or later) there is a certain correlation". Because most students registered WeChat account earlier, and most students in Princeton after the beginning of July before arriving in Beijing registered WeChat account. To this end, Xie Yu in the course of the WeChat group to do a number of repeated experiments, trying to investigate the relationship between the amount of WeChat red envelopes and user experience. So, in order to do the experiment in the end how many red envelopes? Grab 0.01 may not point back, Peking University found that the answer was not randomly assigned red – WeChat secretly tell you this question, under the total of 10 times the total amount of activities to receive red envelopes, each payment of fixed 5 yuan, every time the red number in the 27-32 between. So, the total number is…… 50 yuan. Grab 0.01 may not point back, Peking University found that WeChat was not randomly assigned red envelopes for youth do not concern the amount of red! Let’s look at the conclusion. As mentioned above, the highest amount of money to those who have in common is that they are registered WeChat earlier. Most students registered WeChat account earlier, while the majority of students in Princeton after the beginning of July before arriving in Beijing registered WeChat account, only a few Chinese students before registration.相关的主题文章:
