本文详细介绍了取卡片游戏中《等可能性事件》的类型及它与其它事件的关联,介绍了如何利用它求出不等可能性事件的概率,并以此为根据,改正了书中常见的《求可能性应用题》的错误解法,是小学数学教师提高解题能力的必读参考材料.1.等可能性事件随机试验中每一个可能出现的结果,叫基本事件,每个可能结果(即基本事件)出现的可能性相等,则称为等可能事件.每个等可能性事件的所有条件必须是相同的,而且能够简单地判定出来,才可以看作等可能性事件.如果不能,则不能视作等可能性事件.
This paper introduces in detail the types of “probable events” in the card game and its association with other events, introduces how to use it to find out the probabilities of unequal events, and based on this, corrects the common The “wrong way to solve the problem” is the primary reading mathematics teachers to improve the ability of reading the necessary reference materials.1.Perceptional events Random each test may occur, called the basic event, every possible outcome (That is, basic events) are equal, they are considered as possible events, and all the conditions of each equally-probable event must be the same and can be simply judged before they can be considered as equal-probability events. , It can not be considered as a probable event.
