高考中考查随机变量分布列与概率知识主要体现在它在实际生产或生活中的应用,解决这类问题的关键是把实际问题转化为数学概率问题。而要成功转化就必须提高我们的阅读能力,阅读能力的提高是通过我们平时大量的训练而慢慢形成的。下面我们给出以时下热点材料为背景的两道概率题,希望能提高同学们解答概率题型的能力。
Examination of the entrance to the random variable distribution column and probability knowledge is mainly reflected in its actual production or life, the key to solve such problems is to turn the actual problem into a mathematical probability problem. In order to successfully transform we must improve our reading ability, reading ability is improved through our usual extensive training and slowly formed. Here we give the current hot spot material for the background of the two probability questions, hoping to improve students’ ability to answer probability questions.
