Chapter 830 Probability

Bai Youwei spread out the pictures she drew for everyone to see.

"We have been walking for so long, and now we have figured it out. There are twelve horizontal rooms in total. If we mark them according to the numerical sequence from 1 to 12, the Minotaur finally stayed at No. 2, and we are now at No. 12.

Assuming the tauren doesn't move at all while eating, it will have to move at least 8 squares to catch up with us. "

Bai Youwei pointed at the teleportation point with her finger.

"According to common sense, this is a distance that cannot be caught up no matter what, but there are an unknown number of teleportation points in the maze. If I were a tauren, I would choose a location not far from each teleportation point and predict it through Where the player is going, and then selects the corresponding teleport point.

Therefore, if you want to avoid being caught up by the tauren, at least two conditions must be met.

First, avoid all transfer points;

Second, avoid all blind spots. "

Chen Hui said hesitantly: "But now... we are not only near the teleportation point, but also very close to the blind spot..."

Bai Youwei pondered for a while and said: "Let's go one square to the west and then north. If this maze is a 12X12 square, then we only need to move forward nine times to reach the end."

"Are you sure it's 12X12?" Du Lai asked.

"I just said that it is possible." Bai Youwei said, "Whether it is a maze or a game, regular shapes are usually preferred. The most common one is the square. Now we know that there are 12 locks and 12 keys, and the horizontal room It also happens to be 12. If there are also 12 vertically, then this maze is probably a square."

Leonid asked: "So what if you know it's a square?"

"Not much." Bai Youwei lowered her eyes and whispered, "At least when the tauren chases us, we won't be forced into a blind corner again."

"But..." Chen Hui hesitated, "If we want to confirm this... we have to at least go to a dead end again."

They have already walked two "corners", and if they want to prove that the maze is a square, they need to determine at least one more "corner".

When entering a "dead corner", it is very easy to be surrounded by the Minotaur.

Bai Youwei thought for a while and said calmly: "There is no way around it. Even if we know that there is no dead end, we still need to search every room in the maze in order to know the location of each key."

"Then let's go." Shen Mo said calmly, "Get out as soon as possible."

Bai Youwei glanced at him and said, "Let's go west."

The group of people moved one square to the west. When they were herding chickens, Du Lai saw a key in the stone room on the west side, so they moved forward one square and got the sixth key.

"I now believe that this maze may be 12x12." Du said.

Asalina asked him: "Why?"

"Because the probability of encountering a key is very high." Du Lai raised his lips. "If there are as many as a thousand or ten thousand rooms here, it would be almost impossible to pick up the key by luck, right? But if it is 12x12, Then the total number of rooms is 144. Excluding the teleportation point rooms, the probability of picking up the key...may be around 10%."

"Is 10% very high?" Chen Hui couldn't help but ask.

Du Lai smiled and asked her: "Do you know Shuangseqiu?"

Chen Hui nodded, "I know, what's wrong?"

"The lowest prize for the double-color ball is the fifth prize, with a bonus of 5 yuan. The probability of winning is about 6%." Du said, "The probability of us picking up the key is much higher than the probability of winning the double-color ball."

Bai Youwei held the key, thought for a while, and said, "We have to go back and put the key in the stone room on the west side of the teleportation point."
