20 15 Jilin provincial examination has come to an end. According to the examinee's memory, the most important feature of the number of various examinations in Jilin Province on 20 15 is the restoration of the proposition route before 20 13. The mathematical operation and numerical reasoning in Grade A and B papers are all five questions, and the mathematical operation is relatively simple, and the test sites involved are all ordinary test sites. I believe that candidates are familiar with these common test sites and get a score. However, in the 20 14 exam, numerical reasoning and other issues are rarely examined. Perhaps most candidates do not take review as the key content, but the exam is very difficult. According to the teacher's explanation of numerical deduction in the existing course of Jilin Tuhua, it is enough to solve 90% of the problems.

? However, the investigation of Jilin civil service examination data analysis in 20 15 has also changed, from three 15 questions a year to two 10 questions, but it does not affect the candidates' answering questions at all, because the test sites involved in data analysis must be within the preparation scope, as long as the data analysis part is properly placed in the answering process, they will definitely get more than 90% scores.

? According to the examinee's memory, most knowledge points of quantitative relationship and data analysis have been talked about!

? Xiao Ming tossed coins three times in a row to see if the face facing up was written or flowered. Please help him figure out the probability of two heads up.

? Red Collar Training Handout Chapter 8 Exercise 4:

? Someone threw the target into the shape of a unit circle and threw it four times in a row. If it falls on the position of the first quadrant just three times (assuming that the bull's-eye is the origin of coordinates, and the horizontal and vertical directions are the horizontal and vertical axes respectively), please help him calculate the size of this possibility as ().

?

? The above questions are completely similar to the probability of 20 15 Jilin provincial examination. Take Exercise 3 as an example. If Xiao Ming throws a coin three times in a row, and two of the three times are face up, then the rest of the time is face up. The probability of throwing a coin, whether it is face up or face up, is 1/2, which means the required probability is the same. Data analysis and testing center.
