几何概型是区别于古典概型的另一类等可能概型,将研究有限个基本事件过渡到研究无限多个基本事件。求解几何概型的概率,最关键就是分析基本事件的构成以及“测度”的寻找;对于一个具体的问题能否用几何概率模型公式计算其概率,关键是能否将问题几何化,从建立的几何模型入手,来解决概率问题。 The geometric type is another type of probable generalization that is different from the classical one. It will study a limited number of basic events to study an infinite number of basic events. The key to solving the probability of geometric pattern is to analyze the composition of basic events and the search of “measure.” Whether the probability of a specific problem can be calculated by the formula of geometric probability model depends on whether the problem can be geometricized or not. The establishment of the geometric model to solve the problem of probability.
