我们都知道几何概型和古典概型最重要的区别就是几何概型在试验中所有可能出现的结果(基本事件)有无限多个,而古典概型是有限的;也知道几何概型的概率公式为:一般地,在几何区域D中随机地取一点,记事件“该点落在其内部一个区域d内”为事件A,则事件A发生的概率P(A)=d的测度D的测度.但是在真正解决一个几何概型问题时,学生就明显感觉到难度很大,思维很复杂,远比古典概型难得多.那么,如何使学生在解决几何概型问题时得心应手呢?笔者认为还得培养学生的思 We all know that the most important difference between a geometric pattern and a classical pattern is that the geometric pattern has an infinite number of all the possible outcomes (basic events) in the experiment, whereas the classical pattern is finite and the probability of the geometric pattern The formula is: In general, take a random point in the geometric region D, remembering that the event “A falls within a region d of its interior” is the event A, the probability P (A) = d that the event A occurs However, in the real solution to a geometric problem, students obviously feel very difficult, thinking is very complicated, far more difficult than the classical profile so how to make students handy when it comes to solving the geometric problem I think that students have to cultivate thinking
