概率知识是新课程中增加的知识,从近几年各地的中考试卷来看,与概率知识有关的考题分值约占全卷的5%~8%,题型既有选择题、填空题,也有中档难度的解答题。以解答题出现的省份或市占50%左右,这说明概率试题在今后的中考中仍占有相当重要的地位。初中数学中的概率问题,多设置与现实生活联系紧密的情境问题,旨在让学生在解决实际问题的过程中感受到概率知识与实际生活的紧密联系,初步感受概率的思想,进而体验概率在进行决策时的重要作用。
Probability knowledge is an added knowledge in the new curriculum. Judging from the mid-term exam papers in recent years, the scores of test questions related to probability knowledge account for 5% -8% of the whole volume. The questions are both multiple choice questions, There are also mid-range difficulty answer questions. In order to answer the questions appear in the provinces or municipalities accounted for about 50%, indicating that the probationary questions in the future in the exam still occupies a very important position. Probability problems in junior middle school mathematics, and more settings and real life situations are closely linked to the situation, so that students in the process of solving practical problems felt the probability of knowledge and real life are closely linked to the initial feeling of probability of thinking, and then experience the probability of Important role in decision making.
