相对频率 - 乘法规则
几何画板及绘图内容加载中,请稍等……
这个范例演示了如何使用 GeoGebra 构造相对频率的乘法规则。涉及的核心数学概念是概率统计中的相对频率和乘法规则。作图要点包括使用 Textfield, Shuffle, If, Polygon, Element, Append, Remove, TextToUnicode, Line, Segment, Mirror, Text 等命令和对象。适合小学五、六年级学生学习和理解概率统计的基本概念。

AI 绘图提示语参考
画一个包含两个随机序列的图形,两个序列分别代表 x 和 y 坐标,序列中有重复的数字会被去除。图形中有一个正方形,两个圆形和一个直线。正方形的顶点是两个圆形的中心,直线是两个圆形的对称轴。
以上提示语为根据原始绘图命令整理而来,仅供参考。
