What are some of the things that have happened to you with a probability of 0.10 percent?

I was sick and suspended from school in the first year of junior high school, when I was in the third year of junior high school, other classmates were already in the first year of high school, I never thought that my table in the first year of junior high school was sick and delayed for a year before the high school entrance examination, and we became a first-level again, after returning to school, the whole school 12 classes were exactly the same class as me, and the whole class of 64 classmates happened to be at the same table with me.

I was very poor at English when I was studying, and then the kind of student who didn't study much, I was at the same table as me, but he spoke English very well. One day I copied his English gestalt, the kind of paper for a small exam, and then in order to look realistic, I made a few mistakes and sent them all right, and the ones I "wrong" were the ones he was wrong.

When I was in elementary school, after the final exam, the night before I received the result notice, I dreamed that I had scored 97 points in both Chinese and mathematics, and when I went to school the next day and got the report card, I had 97 points in both subjects.

When I was in physics class, I took a coin and said to me at the same table, if it was a word, then I would sleep, if it was a flower, then I would read the extracurricular book, and if it was erected, I would listen to the lecture. The coin spun for a long time, fell to the ground, spun on the ground for a long time, and stood there, but I still happily read an extracurricular book.

When I was in high school, I was reassigned to classes based on grades every year. and a female classmate, who were in the same class for three years. During the college entrance examination, they were arranged together in the last examination room, and there were only 10 candidates in the last examination room. When the university started, I met her at the school gate.

When I was in college, my classmates took me to an electronic arcade. That kind has a kind of horse racing machine. I took a coin from my classmate and stuffed it in, and I actually hit a jackpot.

This is my 1st play, 1st coin. The machine spat out for a quarter of an hour. Then the classmates and the people around them were stunned.

My best friend and I have one in seat 16 in room 12 and seat 12 in room 16, which is the last four digits of the admission ticket number, one is 1216 and the other is 1612, which is really magical.

When I was in elementary school, when I came home from school, the wind blew a piece of paper, and I picked it up and looked at it, and I wrote my name on it in fair calligraphy.

On the way home by bus, I saw a person riding a bicycle that I had lost before, and I decisively asked him to get it back, which means that I found the car I lost on the same day. Coincidentally, right?

I went back from Shanghai with my boyfriend, he went back to Wuxi, I went back to Nanjing, I bought the ticket, when I bought the ticket, I first bought my own, and then bought him one, only to find out that we originally bought the same bus, the same carriage, or the next seat. It's something that's amazing to me.

The inclusion of a zero point indicates that the independent variable x has little or no effect on the dependent variable y.

Confidence intervals are estimated intervals for population parameters constructed from sample statistics. In statistics, the confidence interval of a probability sample is an interval estimate of a population parameter for that sample. The confidence interval shows the degree to which the true value of this parameter falls around the measurement result with a certain probability, and it gives the degree of confidence in the measured value of the measured parameter, i.e., the "one probability" required above.

Solve Steps. Step 1: Find the mean of a sample.

Step 2: Calculate the sampling error error. In practice, it is generally accepted that the sampling error of 100 samples is 10%; The sampling error of 500 samples was 5%; The sampling error was 3% for 1200 samples.

Step 3: Use the "sample mean" calculated in the first step plus and subtract the "sampling error" calculated in the second step to obtain the two endpoints of the confidence interval.

Events with a probability of twenty percent are as follows:If an individual draws a prize, the probability of each person is two percent;

dumplings, 20 of which are filled with three fresh fillings, then three fresh dumplings.

The probability of being late is 20 out of 100;

3. There are a total of 5 courses in Fu Brigade: Chinese, mathematics, English, physics, and chemistry are missing, and if one course is taken as the first class, the probability of not having a course is 20%.
