纵观近几年的高考数学题,概率试题的出现频率很高,一般都以12分左右的大题出现。对于这个比较固定的知识点,应该力争不失分。概率问题求解的关键是寻找它的解题模型,只要模型找到,问题便迎刃而解。从近几年的高考试题看,其试题主要呈现如下五个特点。 Throughout the entrance exam math problems in recent years, the probability of test questions appear frequently, usually with 12 points or so big problems appear. For this relatively fixed point of knowledge, should strive to lose points. The key to solve the probabilistic problem is to find its solution to the problem model, as long as the model is found, the problem will be solved. Judging from the college entrance examination papers in recent years, the test questions mainly show the following five characteristics.
