概率在中学数学教材中占有独特的地位.在近几年的数学高考中概率成为高考命题的一个新热点.如2007年的全国及各地的高考试卷中,有18道试题考查等可能性事件的概率,有14道试题考查对立事件的概率,有15道试题考查互斥事件有一个发生的概率.所以等可能性事件的概率、对立事件的概率、互斥事件有一个发生的概率是高考对概率问题考查的热点和重点.同时,新增加的几何概型也是可能的新热点.那么我们就具体看一看概率的热
Probability occupies a unique position in middle school mathematics textbooks. In recent years, the probability of mathematics college entrance examination has become a new hot spot for college entrance examination propositions. For example, in the 2007 national exams and local high test papers, there are 18 possible questions to examine and other possible events. Probability: There are 14 questions to examine the probability of opposing events. There are 15 questions to examine the probability of mutual exclusion events having one occurrence. Therefore, the probability of such possible events, the probability of opposing events, and the probability of mutual exclusion events have a probability of occurring. Probability issues look at hotspots and priorities. At the same time, new geometric outlines are also possible new hot spots. Then we take a closer look at the
