我们知道,全面准确地深层理解一个个数学概念,是学好数学的前提.对一个数学概念的深层理解,不能简单机械地背诵概念文字,要内化概念背后的深层含意,并加以灵活运用.以下结合具体问题,小议如何深层理解几何概型概念及其运用.一、几何概型概念的深层理解(1)如果每个随机事件发生的概率只与构成该事件区域的长度(面积或体积等)成比例,则称这样的概率模型为几何概率模型,简称为几何概型.
We know that a comprehensive and accurate understanding of mathematical concepts one by one is the premise of learning mathematics.A deep understanding of a mathematical concept can not simply memorize conceptual words mechanically, In the light of the specific problems, how to understand the concept of geometry and its application in depth: 1) The deep understanding of the concept of geometry (1) If the probability of each random event is only related to the length (area or volume) ) Proportional, then called the probability model for the geometric probability model, referred to as the geometric model.
