从古典概型到几何概型,样本点的个数从有限发展到了无限.这使得学生在连续无限的样本空间里判断随机事件的等可能性易犯错误,下面就是教学中的一个常见例子. From classical to geometric models, the number of sample points has grown from limited to infinite, which makes it easy for students to make mistakes in determining the probabilities of random events in a continuous infinite sample space. Here is a common example in teaching.
