纵观近几年高考试题,几何概型问题频频出现,这类问题新颖别致,构思精妙,极富思考性和挑战性.几何概型的概率求解一般分三步:(1)判断试验是否为几何概型;(2)将试验构成的区域和所求事件构成的区域转化为几何图形,并加以度量(如长度、面积、体积或角度);(3)应用几何概型的概率公式求概率.下面结合实例分类解析,旨在探索题型规律,揭示解题方法.
Throughout the college entrance examination examination papers in recent years, frequent occurrence of geometric problems, such problems are novel, exquisite ideas, very thoughtful and challenging. Probability of the geometric general solution in three steps: (1) to determine whether the test Geometry type; (2) transform the region formed by the experiment and the region formed by the event into a geometric figure and measure it (such as length, area, volume or angle); (3) use the probability formula of geometric probability to find the probability The following combination of examples of classification and resolution, to explore the type of questions to reveal the problem solving methods.
