概率知识是高中数学的重要内容,新课改高考对概率知识的考查,主要表现在对古典概型和几何概型的考查,虽概率部分的内容较少,但是所占的分数比重却较大.围绕概率知识的考题在高中数学竞赛试题中也占据重要的位置,成为高中数学竞赛命题的热点.下面就通过具体的例子来看一下概率在竞赛中是如何考查的.
Probability knowledge is an important part of high school mathematics. The examination of probabilistic knowledge in freshmen’s college entrance examination is mainly based on the examination of classical probabilities and geometric probabilities. Although the probabilistic part contains less content, The questions around probabilistic knowledge also occupy an important position in the high school mathematics competition test questions and become a hot topic in the high school mathematics contest propositions.Here we will take a concrete example to look at how probabilities are examined in the competition.
