数学思想是对数学知识本质的认识,是建立数学模型和用数学知识解决问题的指导思想。下面举例说明数学思想在概率问题中的应用。一、方程思想例1在一个不透明的口袋中装有4个红球和若干个白球,它们除颜色外其他完全相同。通过多次摸球实验后发现,摸到红球的频率稳定在25%附近,则口袋中白球可能有()A.16个B.15个C.13个D.12个分析由摸到红球的频率稳定在25%附近,得出口袋中得到红色球的概率,进而求出白球个数。 Mathematical thinking is the understanding of the nature of mathematics knowledge. It is a guiding ideology for establishing mathematical models and solving problems with mathematical knowledge. The following examples illustrate the application of mathematical thinking in the problem of probability. First, equations Example 1 In an opaque pocket, there are 4 red balls and several white balls, which are identical except for color. Through multiple ball-swiping experiments, it was found that when the frequency of the red ball was found to be stable at around 25%, the white ball in the pocket may have () A.16 B.15 C.13 D.12 analysis by touching the red The frequency of the ball is stable at around 25%, the probability of getting a red ball in the pocket is obtained, and the number of white balls is calculated.
