今年9月,全国将有更多的地区成为《全日制义务教育数学课程标准》(实验稿)试验区,其中江苏就有1/3以上的市县进行新课程标准试验.在新的数学课程标准中已经增补了一些新内容,如概率、图形变换等.概率,即偶然事件发生的可能性.本文生动地讲述了概率知识的应用,由“误用”到“正确应用”,颇具启发性. In September of this year, more regions in the country will become the “Mathematics Curriculum Standards for Full-time Compulsory Education” (experiment draft) pilot area, of which more than one-third of the cities and counties in Jiangsu are conducting new curriculum standards tests. In the new mathematics curriculum The standard has been supplemented with new content, such as probability, graph transformation, etc. Probability, that is, the possibility of accidental events. This article vividly describes the application of probability knowledge, from “misuse” to “correct application”, quite inspiring .
