The problem of probability is that if you use this lottery to check, if you recite, you don't know who the next person will recite. Some people just like this uncertainty, because after you recite this check, it's basically your turn. This feeling is like going to the execution ground. This feeling is very uncomfortable, but if you make this bamboo tube and carry it on your back, you can avoid it.
Uncomfortable feeling For many students now, reciting is a very terrible thing. Many students don't want to recite, or even if they recite themselves, they are very nervous when it's their turn. Using this lottery to recite can avoid this uncomfortable feeling, and maybe it will be their turn. This feeling is still relatively good, so it can be welcomed by the majority of students.
Generally speaking, this method of reciting by drawing lots is really popular with students, because if there is uncertainty, you won't know who is next, which can reduce this uncomfortable feeling.
