For all of them mathematics is a powerful theoretical and practical tool without which no scientific calculation and no engineering and technology are possible. 数学方法是物理学、机械学、工程学和其他自然科学的基础，对所有学科来说，数学是有利的理论和应用工具，没有数学就不可能科学计算工学和技术。 Unit 2 2【random variable随机变量】 【expert system 专家系统】 【probability distribution概率分布】 【density function密度函数】 【computer simulation计算机仿真】 【sample space样本空间】 【statistic inference统计学的推论】 【impossible event不可能事件】 【standard deviation标准偏差】 【relative frequency相对频率】 Translation into Chin
