This week, I learned statistics and possibility. Example 1 mainly studied the possibility and decided to kick off by tossing a coin. Because both sides have the same possibility, it is fairer. Example 2 After learning the game of parcel delivery, I learned that it is fair to play this game, because there are 18 students in a * *, and the possibility that the flowers fall into everyone's hands is that boys and girls can perform programs, which can be said to be true. Through our practice and the teacher's teaching, we have calculated that the play of scissors, stones and cloth is fair, because their possibilities are equal. Example 4 studies the median, and we know that the advantage of the median is that it is not affected by big data or small data, so it is sometimes more appropriate to use it to represent the approximate level of all data. Example 5 learned to find the median of even numbers, add the two middle numbers and divide them by 2.

Haha, although this week has passed like water, I will never forget what I learned, because I succeeded again. I hope I can succeed next time, cheer for me, believe me: I will not live up to the teacher's expectations!
