Chapter 8: Official Cheating
The male college student who was ordered was called Cheng Shuo, for some reason, he didn't feel underestimated at all, although it was a simple question, he felt that he was recognized, and for some reason, he inexplicably had a sense of admiration for Su Lin.
Maybe it was the other party's extraordinary computing ability, or maybe it was the other party's calm and unhurried bearing in this situation that infected him, so he cooperated with Su Lin's explanation very much, and replied: "There are ninety-five kinds in total. ”
No one asks why it's not ninety-six, because you can't put 1 in the first grid, otherwise the cycle will just end.
Su Lin nodded, "What about the second one." ”
"Because the first slot has already used up one number, there are only ninety-four."
Cheng Shuo gave the answer after a little thought.
Su Lin pointed to the subsequent lattice, "And so on, with a cyclic possibility of length 96, there is a total of 95 times 94 times 93 and so on multiplied to 1." ”
Su Lin didn't use the term factorial, mainly to facilitate the understanding of death row inmates.
He continued to ask Cheng Shuo, "How many permutations are there in those 96 grids to put numbers in them?" ”
"Steps of 96...... Multiply from ninety-six to 1. ”
Cheng Shuo originally wanted to talk about factorial, but remembering that Su Lin didn't use this kind of statement, he felt that he shouldn't use it either.
Su Lin squatted down and wrote a formula on the side, which was 95X94X93...... 1, BELOW IS 96X95X94...... 1;
"Wow, Brother Su is so powerful, the repetitive part was repetitive, so ...... The probability of a cycle with a length of 96 is only 1 in 96!? ”
The girl who had been watching from the side exclaimed, although she didn't know what the significance of Su Lin's calculations was, she just felt that it was very powerful.
Several other strangers also frowned and pondered, they felt that Su Lin's calculation of the possibility of the cycle length was the key to whether they could leave the prison of the Demon Hunting Division, but after figuring out the principle of Su Lin's so-called winning method, they still felt that they couldn't break it through a membrane.
Su Lin smiled, he is a bit eccentric, he enjoys the feeling of being admired by others in the process of reasoning or explaining, or he is a bit of a good teacher, he is a well-known good tutor when he was a work-study student in college.
However, time was limited, so he didn't go around the bend to continue to ask Cheng Shuo, but continued to explain: "And so on, the probability of a cycle of length ninety-five appearing is one in ninety-five, the probability of a cycle of length ninety-four appearing is one in ninety-four, and until the length that determines the number of times our fate is determined, that is, forty-nine, the probability of a cycle of length forty-nine appearing is one in forty-nine." ”
Su Lin stood next to the formula, "I also explained it just now, so some people should understand that it is impossible for the same number to appear in two cycles, and those are randomly arranged to appear in the possibility of loops with a length of more than 48, if these situations occur, we will lose, then ...... What is the probability of a long cycle? ”
He had a smile on his face, although no one had his superhuman computing power, but everyone present at this time who had a certain mathematical foundation noticed that these probabilities definitely did not add up to more than ninety percent!
Su Lin saw that no one rushed to answer, and was very satisfied, "It's 0.6879659724913229, we think the other way around at this time, there is no long cycle, that is, the probability that the loops that appear are all of 48 and below in length is 0.3120340275086771, oh, everyone understands that it is 31 percent." ”
"The win rate has increased from almost zero to three!"
Cheng Shuo shouted in surprise, "Because every time we enter the room, we just open the box to find the number, but the number is not taken away, in the same round of the game, after we leave, the guards will only cover the box again, if the boxes in this round meet the conditions that the cycle length is all below forty-eight, we can clear the customs in one round!" ”
Xiao Gang scratched his head, in fact, he didn't understand, "But even so, there is still only a three-percent winning rate." ”
Although he said this, he already felt that Su Lin's mind was outrageously strong, and he raised the probability that was infinitely close to zero to a probability that he could gamble on, which made him admire the other party's mind from the bottom of his heart.
Su Lin didn't laugh at Xiao Gang, "Brother Xiao, you forgot, the Warden has given us tangible clearance benefits, before the ancient hourglass falls, we can try this game to our heart's content, that is to say, if we fail this round, we can also let the guards reset everything in the room and start over, you may think at first that the Warden specifically stated that every time the game is reopened, everything will be reset to avoid us remembering which box the number is placed in, but in fact, if the Warden of this game has a plan to give us a chance to clear the customs, That's a big perk indeed. ”
He glanced at the ancient hourglass, it had only been about half an hour since he began to explain, and they still had plenty of time.
"If you move quickly, it will only take about a minute for a person to go in, and a round of the game is at most an hour, and in fact, according to my plan to open the box, if it is impossible to clear the level, there will soon be failure, then the game will start again directly, there are still more than twenty-three hours left, theoretically if we keep failing, the time to remove the guards to reset the room, enough for us to try fifty times is more than enough."
The corners of Su Lin's mouth hooked, "And how low is the probability of failing fifty times, so I don't need to explain it, right?" ”
The scene was silent for a while, and then a carnival-like roar erupted, but the prisoners at the scene did not rush to the room for a while, but looked at Su Lin, obviously waiting for instructions, for fear that his dull brain had made a mistake, and there was some arrangement for the order of entry.
Looking at this scene, Su Lin stretched, "Big brother, go in and try it, hurry up, we can go out for lunch." ”
"Hahahaha......"
At this time, the man sitting on the sofa in the monitoring room smiled happily, and he pointed to Su Lin on the screen, "This kid is interesting, what about his information, call it up." ”
"Su Bai...... Fraudster? Sentenced to death? ”
The man sitting on the sofa took a sip of tea, looked at the information on the tablet, and was a little puzzled.
"My lord, the person he deceived has something to do with ......"
Mu Chen explained, "You can see when you look back. ”
He knew how powerful the man sitting on the sofa was in the Lingwu Empire, and the person in front of him was Lu Zhenguo, the deputy commander of the Demon Suppression Division of the Lingwu Empire, and after this game was launched in prisons all over the country, he patrolled everywhere.
The so-called test, in fact, mostly depends on the mood of this master, if he sees it, then it can be regarded as passing the test, and then someone will be arranged to take away the death row prisoners who have passed the test, and the demon hunting department will be responsible for training, and a very small number of people may be directly arranged to the post.
Lu Zhenguo looks very young, only in his early thirties, wearing a decent gray Tang suit, which adds a bit of old-fashioned air to him, but in fact, he is indeed not young, a hundred and seventy years old, only because he is too powerful as an alien spirit, so he looks young.
At this time, Lu Zhenguo's fingers flicked the tablet, "Huo, it turned out that the people from the Ministry of Commerce were embarrassed, no wonder they were brought in, but why are they locked up in the dungeon of our Demon Hunting Division?" ”
Since the Demon Hunting Division is called the Demon Hunting Division, of course, its duty is mainly to capture the monsters that cause harm to the world, and sometimes humans will be locked in, but those are all human beings involved in monster cases, for example, some death row prisoners are 'human rapists', serving monsters as lackeys, deceiving the same clan, and feeding humans to the mouths of monsters.
The dungeon of the Demon Hunting Division is dirty and dilapidated, and the environment is old, but in fact, this is not a place for people to prepare, of course, the Lingwu Empire also has a dungeon dedicated to people, and the environment will be much better and more modern.
For example, those sentenced for fraud are generally tried according to the common laws of human beings, and sent to human prisons, not to the dungeons of the Demon Hunting Division.
Lu Zhenguo said, he looked at Mu Chen, let Mu Chen's face under the mask break into a cold sweat, and hurriedly explained: "My lord, you also know that over the years, because of a few saints, the demon clan has been weak, but there is more chaos within the human race, and all prisons can't be closed, and the dungeon of our Demon Hunting Division is empty all year round, and many of them have been sentenced." ”
Lu Zhenguo didn't look at Mu Chen again, his fingers sliding, and he also saw the verdict behind the information, and he also had a transfer record, knowing that what Mu Chen said was true.
"Well, Su Bai, this kid is interesting, I will arrange for someone to take him away."
Lu Zhenguo put down the tablet and looked at Su Lin on the screen with interest.
After watching Su Lin analyze, he let many death row inmates enter the room to try, but soon the first round of death row inmates failed, he smiled, "Tell the jailer to start the next round of the game and deliberately arrange a long loop when assigning numbers." ”
Mu Chen was a little puzzled after listening to Lu Zhenguo's words, and no matter how much the official tricks in the game seemed too out of place, he looked at Lord Lu's demeanor just now, and seemed to appreciate this death row prisoner named Su Bai very much, and said that people would take it away, why did he temporarily increase the difficulty?
It's not so much about the difficulty, if the jailers manually set up a long loop, wouldn't it directly block the way for these death row inmates to clear the game?
Is it because there will be trouble with the release of all these death row inmates?
Mu Chen's heart quickly overturned this idea, since he had distinguished between the words 'leaving' and 'freedom' from the beginning, that is, the Demon Hunting Division had already had a plan to allocate those who left the death row prisoners.
There are many ways to deal with those vicious death row prisoners, they release people, it does not mean that they will give up supervision, they can be exiled to the dangerous border, and there will be their own border army management there, and those who do not obey discipline will die, and those who obey discipline may also die in the struggle with the demon clan, which can be regarded as atonement for their previous sins.
He was just curious about why Commander Lu was operating in the dark, was it a further test for that young man?
In this way, if the official cheat directly sets up a long loop, how can the death row inmates win!?
