可能性排序

Ordering Likelihoods

比较不同事件发生的可能性,并按从最不可能到最可能的顺序排列——包括结果不相等的情况,例如袋子里某种颜色的圆片比另一种多,或者转盘上各区域大小不同——并用日常语言解释推理过程。

Compare the likelihood of different events and order them from least to most likely — including situations with unequal outcomes such as a bag with more of one colour than another, or a spinner with sections of different sizes — and explain reasoning using informal language

评估问题 / Assessment

如果袋子里有8个红色圆片和2个蓝色圆片,{{name}}是否明白抽到红色圆片比抽到蓝色圆片的可能性大得多?他们能否将不同事件按从最不可能到最可能的顺序排列?

If a bag has 8 red counters and 2 blue ones, does {{name}} understand that picking red is much more likely than picking blue — and can they put different events in order from least to most likely?
