离散型随机变量的概率问题是近几年高考命题的亮点和热点。而且高考命题者注重知识的交汇与综合,随机变量的概率问题常常与统计、方程、数列、不等式、解析几何、立体几何等知识相互交汇融合、渗透,使问题的情景新颖而别致。下面举例归纳随机变量与其他知识的交汇。
The probability of discrete random variables in recent years the college entrance examination proposition highlights and hot spots. Moreover, college entrance examination subjects pay attention to the intersection of knowledge and synthesis. The probability problems of random variables are often mixed with the statistics, equations, series, inequalities, analytic geometry and solid geometry to infiltrate each other, making the situation of the problem novel and unique. The following example summarizes the intersection of random variables and other knowledge.
