概率可以帮助人们了解情况,发现规律,从而做出合理的判断和预测,因此概率问题便成了近年来命题的新亮点.命题者巧妙以摸球、抛硬币、转圆盘、抽扑克、摸卡片、翻象棋等我们既熟悉又感兴趣的活动为载体,设计成概率中考题,以考查我们应用数学知识分析问题和解决问题的意识和能力.现以摸球题为例,剖析这类题的解法. Probability can help people understand the situation, find the law, and make reasonable judgments and predictions. Therefore, the probabilistic problem has become a new bright spot for propositions in recent years. The propositionalists cleverly touch the ball, toss a coin, turn a disk, draw poker, and touch. Cards, flip chess, and other activities that we are both familiar with and interested in are carriers, designed into probabilistic exam questions, to examine our knowledge and ability to analyze problems and solve problems using mathematics knowledge. Now we will use ball games as an example to analyze such questions. The solution.
