同学们在学习古典概型与几何概型时,应明了古典概型与几何概型题型的特点及相关的概率问题.古典概型问题一般通过列举来确定所有基本事件数及有利于某事件发生的个数,并根据事件发生的等可能性加以解决.而几何概型问题往往通过确定某事件发生所构成的区域,进而将问题转化为几何面积问题来加以解 When students study classical patterns and geometric patterns, they should be aware of the characteristics of the classical and geometric patterns and the related probabilities. The classical patterns usually determine all the basic events and are conducive to certain events by enumeration The number of occurrences, and according to the probability of occurrence of the event to be solved.The geometry of the problem often through the identification of an event formed by the region, and then the problem into a geometric area problem to be solved
