同学们认识了许多随机事件,逐步明白了概率就是描述随机事件发生可能性的大小,感受到概率的作用,比如彩票中奖率低的原因,转盘游戏对双方是否公平.同时也能计算简单随机事件发生的概率,但是同学们在学习中也产生了误区,认为所有的随机事件发生的概率都能计算.“利用频率估计概率”一节为同学们提供了大量的试验,借助试验模型获
The students realized many random events and gradually realized that probability is the size of describing the possibility of random events and the effect of probability such as the reason why the lottery winning rate is low and whether the turntable game is fair to both parties and can also calculate simple random events Probability of occurrence, but students also produced a misunderstanding in learning, that all the probability of occurrence of random events can be calculated. “The use of frequency estimation probability” section provides students with a large number of experiments, with the help of experimental model
