摘要
几何概型是新课标的新增内容,对于几何概型,关键是要构造出随机事件对应的几何图形,利用图形的几何度量来求随机事件的概率。一般可以分成如下几种概型问题:①长度型几何概型问题;②角度型几何概型;③面积型几何概型;④体积型几何概型。
Geometry is a new addition to the new curriculum standard.For geometric probabilities,the key is to construct the geometry corresponding to the random event,and use the geometric metric of the graph to find the probability of the random event.Generally can be divided into the following types of general problems:1 length geometric profile problem 2 angle geometry profile 3 area geometry profile 4 volume geometry profile.
