A long novel is usually composed of several chapters, each of which usually contains an independent story. Therefore, if there are two different novels, one volume each and a total of eight volumes, then each of them can be written independently as: Volume 1: - Introduction to the protagonist and the background of the story - The First Appearance of the Protagonist and Encounter with the Villain - The protagonist begins an adventure to defeat the villain - The protagonist gets an important clue and begins to investigate further Volume 2: - The protagonist continues his adventure in search of new clues - The protagonist discovers a new enemy and fights fiercely - The protagonist wins and gains new power - The protagonist returns to the past and tries to stop the development of history Volume 3: - The protagonist returns to the past and fights with the protagonist - The protagonist has an intense conversation with his past self - The protagonist discovers the mistakes he made in the past and tries to correct them - The protagonist and his past self win and change history Volume 4: - The protagonist continues his adventure in search of new clues - The protagonist discovers a new enemy and fights fiercely - The protagonist wins and gains new power - The protagonist returns to the future and tries to stop the development of the future Of course, this was only a possible structure. In fact, the structure of a novel could be more complicated and diverse.

The two different novels were composed of the first, second, third, and fourth volumes. Each volume had one copy, making a total of eight copies.

A long novel usually consisted of the first, second, and third volumes, each volume consisting of one book. Such a novel usually had three volumes or eight books. However, this is just a common way of organizing a novel. Sometimes, a novel may have a different number of volumes or some volumes may not be a single book.

If a novel with three volumes is randomly placed on the same shelf, the probability of each volume from left to right or from right to left being the first, second, or third volume is?

假设这部小说可以被排成 $n$ 册那么每册的位置可以表示为 $(i_1 i_2 i_3)$其中 $1 \le i_1 \le n$$1 \le i_2 \le n$$1 \le i_3 \le n$。 我们考虑将该小说排放在书架上的情况一共有 $C_n$ 种可能的排放方式。对于任意一种排放方式第一册的位置可以是 $(1 1 \dots 1)$第二册的位置可以是 $(i_1 i_2 \dots i_1)$第三册的位置可以是 $(i_2 i_3 \dots i_2)$。 对于任意一个可能的排放方式各册自左到右或自右到左恰好为第一二三册的概率分别为 $\frac{1}{n} \cdot \frac{1}{n} \cdot \frac{1}{n}$。 因此总的概率为: $$ \begin{aligned} P &= \sum_{n=3}^4 \sum_{C_n=C_n(n)} \frac{1}{n} \cdot \frac{1}{n} \cdot \frac{1}{n} \\ &= \sum_{n=3}^4 \frac{1}{n^3} \\ &= \sum_{n=3}^4 \frac{1}{n^2} \cdot \frac{1}{n} \\ &= \sum_{n=3}^4 \frac{1}{n} \\ &= 1 \end{aligned} $$ 因此这部小说任意排放在书架的同一层上各册自左到右或自右到左恰好为第一二三册的概率为 1。

The translation of the first sentence was: One day, I came to an old castle and there was sad music coming from inside. As I walked along the corridor, I heard a melodious song and followed the sound to a room. There was a woman in the room. She was holding a zither and singing. Her voice was clear and melodious, like a clear spring, which deeply moved me. The translation of the second sentence was: Then I came to a mountain peak with beautiful scenery and fresh air. I walked along the mountain road and saw an old man feeding an injured bird. He bandaged the bird's wound and fed it, which made me feel the beauty and warmth of nature. The translation of the third sentence was: Finally, I came to a forest where the trees were lush and the flowers were bright. I walked in the forest and saw a cute little rabbit jumping and playing. I followed it and felt the power and beauty of life. The fourth translation was: These feelings made me deeply feel the beauty and preciousness of life. They made me cherish every day and be grateful to everyone and everything I met in my life.

Okay, I can help you create a mind map for the first unit of the fourth grade mathematics. First of all, we need to understand the theme and content of this unit.
