Instance game: I signed a pact with the gods, and the gods accused me of cheating

Hearing this, the little girl was stunned.

"How about I go? I'll just open a door..."

In the pitch-black environment, Qin Shang's attention was completely focused on the front, and he did not notice that the mood of "Urine is the teardrop of the bladder" behind him had changed again.

She spoke in a quiet tone, minding her own business.

"Didn't the observation log say I would die in the Black Tower? Then the door I opened must also be a death door. Once I enter, the rules will help you eliminate the death door, and the only one left is the life door."

Hearing this, Qin Shang's face darkened.

He tilted his head and felt the warmth of the girl's breath hitting his ear, and his brows frowned even deeper.

"Don't make me whip you."

At this moment, the other players blocking the gate also noticed Qin Shang who was late, and some of them suddenly had their eyes brightened.

"Look, here comes Number 7! Number 7 is smart, he will definitely be able to think of a way out."

"Hey! Do you have any good ideas? Number 7..."

"We're running out of time. We've been stuck here for a long time."

Swish!

All eyes fell directly on Qin Shang.

The other staff members who escaped also looked at Qin Shang at this moment.

Obviously, even though they were "Observers", they did not have the foresight to know the game content of this copy designed by the "Thunder King" himself.

The classic three-door problem.

The next moment, Qin Shang looked at the three doors at the end of the corridor. A cold sweat slid down his forehead and an idea flashed through his mind.

Suppose there are three doors in front of you, two of which are doors of death, and one is a door of life.

Once you select a door, you don't need to push it open.

Instead, one person will eliminate the dead doors among the other two doors except the one he chooses.

For example, there are three doors A, B, and C in front of you.

When choosing one of three randomly, the probability of choosing the life gate is definitely 1/3.

But if after you have chosen a door, someone tells you the specific location of the dead door among the other two doors, and then asks you whether to choose to change the door, you can change your original choice.

At this time, most people's instinct is not to change, because in their opinion, the probability of choosing a living door is 1/3 whether changing or not.

But in fact, at this time, the probability of choosing the life gate when changing gates is higher.

From a purely probabilistic perspective...

If the three doors are A, B, and C.

A is the gate of life, B and C are the gates of death.

Select A for the first time.

When someone pushes open one of the other two doors and tells you that it is a dead door, ask yourself whether to change doors.

If you choose to change the door, I'm sorry, you will definitely die after changing the door. After all, the door you chose at the beginning was the door of life.

But if you choose B the first time, and then another dead end is opened according to the rules, someone opens C to help you eliminate a dead end.

If you choose to change the door at this time, you will choose the life door A.

Similarly, if you choose Death Door C for the first time, according to the rules, someone will help you push open Death Door B among the other two doors.

If you choose to change the door at this time, you can also choose the life gate A.

So you see, whether you change the door or not, after choosing a result in the first 1/3, if you choose to change the door later, you will have two possibilities of survival, so after changing the door, the probability of choosing the door of survival actually becomes 2/3.

Of course, the reverse is also true...

If you choose A at the beginning and insist on not changing the gate, OK, then you will choose your birth gate through the game.

But if you choose B at the beginning and insist on not changing the door, you will walk into a dead end.

The same goes for C...

When you initially choose the dead door C, if someone helps you push open the dead door B and asks you if you want to change doors, but you still insist on your own opinion, then you will still step into the dead door C.

In other words, if you insist on your own opinion, the probability of death is 2/3 and the probability of survival is only 1/3.

But this... is probability after all, it's a gamble with your life!

The next moment, Qin Shang calmed down and shouted towards that side.

"Choose the first door, the first one on the left. The Swindler hidden class hint tells me I should choose the first door..."

Let any of these people help you activate the prompt first and eliminate a dead end.

"No way! Dude, aren't you 'Python Swallowing Dragon'? Big brother, how come you're a fraud and a lawyer? A lawyer... also has hidden hints about the fraud profession?"

At this time, No. 5, who was wearing prisoner uniform No. 3, turned his head and glanced at Qin Shang with a strange look in his eyes.

Hearing this, Qin Shang's heart skipped a beat and his throat tightened.

Damn it, I was so nervous that I forgot about this!

Gan!

This line comes so easily to mind when trying to cheat someone.

"Slip of the tongue, I meant... This is the hidden clue about the Con Man profession of the girl behind me... And one more thing, don't forget number 3, the guy wearing number 5's uniform is Dr. Herman!"

"He built this base. How could he not know where the exit is? Is he deliberately blocking us here?"

The next moment, Qin Shang's face turned black, and he immediately retorted with two sentences, trying to shift the blame.

Let you talk too much!

After hearing this, the other players came to their senses and looked at No. 5 who was wearing prisoner uniform No. 3.

"Yeah, you're Dr. Herman, how come you don't know which of these three doors is the exit..."

"Is your mission different from ours? I'm afraid it's not your mission, but to let us players die here?"

"Yeah, your mission won't conflict with ours, right?"

The others all looked at No. 3 who was confused.

Just as the latter was about to speak, he felt the pain of forgetting his vocal cords at home again. He opened his mouth to explain but couldn't utter a word for a long time.

Qin Shang, who was not far away, slowly put away the blackboard eraser and then turned his head.

"Girl, don't you know which of those three exits is it?"

The real Dr. Herman is on his back.

If the doctor knew the answer, he probably wouldn't have said that he wanted to take the initiative to help him test it out.

Sure enough, the next moment, a girl's bitter laugh came from behind him.

"According to the setting, Dr. Herman had no intention of leaving after building this experimental base. These three doors are likely the final checkpoints designed by the Divine Path. In real history, Dr. Herman likely didn't find his conscience and continued conducting cruel human experiments until the base was destroyed or his life came to an end, leaving him trapped in this base."

Hearing this, Qin Shang spat lightly...

"Then we have to find a way to eliminate a dead end first!"

As soon as this thought came to mind.

The guy wearing prisoner uniform No. 1 rolled his eyes and suddenly shouted at the top of his voice.

"Brothers, since Dr. Herman doesn't object, the first door is the escape route. Push him through."

Fuck!

Ruthless!

Before Qin Shang could speak again, he heard No. 1 give an order and several players swarmed forward, leaving No. 3 without any ability to fight back.

Don't forget that although the martial artist is strong, he has no magic resistance.

It was obvious that there were professional hypnotist players among these people. It was visible to the naked eye that as soon as No. 3 raised his hand to resist, his eyes suddenly became confused, his body swayed twice, and he was dragged into the first door.

Immediately afterwards, a new message popped up in the attribute panels of all players!

[The door in the middle is the death door]

Qin Shang's face lit up with joy.

If the three doors in front of us are divided into 1, 2, and 3 from left to right, then the door that No. 3 was pushed and stumbled into just now is Door 1, and the information we get now is that the middle door is a dead door.

Therefore, door 2 is a death door and there is no escape. In other words, one of 1 and 3 is a life door.

"Unfortunately, when No. 3 crashed into Door 1 just now, I looked inside and couldn't see anything at all. It was a completely distorted space. I guess Shenlu has designed a trick behind the door to prevent players from influencing the final result by the first warrior to choose the third door."

He thought of this and glanced at the countdown.

Twenty seconds left.

I immediately picked up a pen and wrote in the observation log.

【Three Doors to Escape from the Cage】

Then he immediately activated [Observation]!

Now that we know that Door 2 is the dead door, the remaining two doors are eliminated. According to the three-door effect, the first door that Door 3 enters is equivalent to the player randomly choosing a door with a one-third probability. After choosing, the game tells the player which of the other two doors is the dead door. At this time, the player is given the opportunity to choose again. After changing the door, the probability of choosing the living door is 2/3, while the probability of choosing the living door without changing the door is only 1/3.

[So from the perspective of probability, changing the door is the optimal solution]

However, since this dungeon was designed by the beta tester, the player 'Thunder King', the true gate of life is likely the gate of death. 'Thunder King' is a serious person and would not allow players to reach this point where life and death are determined by so-called luck. He is a devil who prefers to play with people's hearts and use so-called power to break others' mentality.

Then, the operation that fits the personality of the 'Thunder King' is likely to be the life gate, which is actually the death gate, and the death gate is actually the life gate. In other words, no matter which door is the first selected in the three-door problem, or which door is eliminated, the true passage is the one that was eliminated. Because normal players will definitely not think of this, this will lead everyone to either choose door 1 or door 3, thus ignoring door 2.

【Observation】Results are presented.

The wavy font began to twist and finally turned into a line of words.

On July 7.11th, the "licking cockroach's feet" rushed towards Gate 2 with "urine is the tear of the bladder" and successfully escaped from the ball cage...
