概率与统计的交汇试题.它们是以实际应用问题为载体,以排列组合和概率统计等知识为工具,以考查对五个事件的判断识别及其概率的计算和随机变量概率分布列性质及其应用为目标的中档题,预计这也是今后高考概率统计试题的考查特点和命题趋向,下面对其考点进行分析,希望能开阔
The intersection of probabilistic and statistical test questions. They are based on practical applications as a tool, and use knowledge such as permutation and combination of probability and statistics as a tool to examine the judgment and recognition of five events, the calculation of their probabilities, and the probability distribution of random variables. The application of the mid-range title as a goal is expected to be the examination feature and propositional trend of the future college entrance examination probability statistics test. The following analysis of its test sites is expected to open up.
