几何概型的特征是试验结果的无限性和每一个试验结果出现的等可能性,它是高中概率部分的一个难点,高考中常以选择、填空题形式出现.要理解并灵活应用几何概型解决相关问题,需要把握其特征.如果一类随机试验具有如下两个特征:(1)进行一次随机试验相当于向一个几何体G中取一点; Geometric features are characterized by the infinite test results and the possibility of each test results appear, it is a high school probability part of a difficulty, the college entrance examination often choose to fill in the blank form to appear to understand and flexible application of geometry to solve Related issues, the need to grasp its characteristics.If a class of randomized test has the following two characteristics: (1) a random test is equivalent to taking a point in a geometry G;
