The audience of the Panda Country went from Ivan helpless to smooth, and it only took about 10 minutes, this level of reasoning against the sky and the ability to adapt to emergencies made the audience feel frightened and more shocked and frightened!

It wasn't until they saw Ivan successfully clear the customs and the tightrope was untied by the staff that all the people were relieved.

At this time, the barrage in the live broadcast room surged.

"I can see that Ivan is adapting to the paradox in the front, and the second half is in his glory, well done, Ivan!"

"It's too difficult, what I'm talking about is that Jiang Zhe's method is too difficult, and after a simple comparison, you can find that our Ivan solution is a little more easy to understand!"

"Yes, I went to the Xia Guo live broadcast room to see Jiang Zhe's solution before, and it was so close that my scalp was numb, and it dawned on me when I watched our Ivan, I didn't expect the paradox to be solved like this, and Ivan only listed three options to successfully clear the customs!"

"In fact, if you think about it deeply, Ivan's explanation is really easy to understand, even a junior high school student can understand it."

At this time, within the group of experts of the cat and bear country.

The experts paused, intently, the reasoning and solution that Ivan had previously conceived.

Without too much cumbersome reasoning, it directly converted the three doors into three options, and it is also the most refreshing choice!

Regardless of Ivan's choice, as long as his first choice of Red Door is not a Ferrari, he has a 2/3 chance of passing this level.

If Ivan chooses the wrong one the first time, Game Ove

！

After a while, there was a discussion in the conference room about the aftermath of the disaster.

"The most important thing is the first choice!"

"That's right, once Ivan picks a Ferrari for the first time and then changes his choice, he loses this level!"

"I didn't expect there to be so many pits in here, if I had gone, I might have failed in 19 minutes!"

"Actually, this level is a godsend for mathematicians, and I can imagine the excitement of a mathematician when he encounters this paradox or problem!"

“...”

After watching the live broadcast, the old man in the black suit led by Pidlov showed a relieved smile on his face.

Ivan entered the dungeon, and it was really much more reassuring than Michal!

Maybe Michal is tough, but it's not as good as Ivan!

He turned his head to look at the male technician in the black suit on the side, and asked, "How did the Army Department handle the matter of sending snipers to the capital to die without authorization?" ”

Previously, there was a non-commissioned officer of the Army Department on Moxico Square, who sent a sniper to observe at the top of the building and was sent into the weird to test the high-energy particle cold weapon knife, but the sniper's superior ordered to ignore it, and there was no retreat and rescue plan.

After Ivan learned about this later, he hurriedly called the leader of the Panda National University and asked to do it himself.

When the big leader learned the information, he was furious.

As for the results of the processing, Ivan was passed into the 13-star dungeon before he heard it.

The technician said without thinking: "The non-commissioned officer's name is Ilyich, the rank of lieutenant, he has been dismissed, he has committed an unforgivable crime, and is currently waiting for the military court to deal with it, after all, it is good to deal with this strange matter, but Ilyich's approach is wrong, and he has offended Mr. Ivan in disguise, it is estimated that he will be given a symbolic punishment and be imprisoned for several years." ”

Hearing this, Pidlov nodded silently and sighed: "I hope Mr. Ivan will not blame us." ”

At this point, in-frame.

Ivan got into the red Ferrari and was about to drive before.

The host in a black suit walked over and leaned outside the main driver to look at Ivan, who saw this and asked curiously, "Is there anything else?" ”

I saw the host ask curiously: "What is the Bayesian formula, tell me, and I will reveal the next level to you." ”

As soon as these words came out, Ivan was stunned, is this guy a human or weird or something else, is he so passionate about mathematics?

Ivan thought for a moment and explained directly: "It is used to describe the relationship between two conditional probabilities, such as P(A|B) and P(B|A)。 ”

"Following the multiplication rule, it is possible to derive: P(A∩B) = P(A)*P(B|A)=P(B)*P(A|B)。 The above formula can also be deformed as: P(A|B)=P(B|A)*P(A)/P(B)。 ”

"There is a basic tool in Bayesian statistics called the Bayesian formula, also known as Bayes' rule, and although it is a mathematical formula, its principle does not need to be numerical to understand."

"If you see someone who is always doing something good, that person is most likely going to be a good person."

"That is to say, when you cannot accurately know the nature of a thing, you can rely on the number of events related to the specific nature of the thing to determine the probability of its essential properties."

"To put it mathematically, it is this: the more events that support a property, the more likely it is that property to be true."

"I just used the elementary mathematical logic solution of your three red doors, not the practical Bayesian formula."

As Ivan's words fell, the middle-aged male host showed a relieved expression, "So that's the case, it seems that the mathematics in your world is very advanced!" ”

Without giving Ivan any chance to react, the host smiled and said, "I will wait for you in the 'Court of Paradoxes', and we will see you soon, respected Mr. Ivan!" ”

As soon as these words came out, the middle-aged male host suddenly turned into a golden light and dissipated here.

Looking at the faint golden particles in the air, Ivan was stunned, and suddenly his eyes narrowed, and he noticed a key word: [your world].

"Is this guy human, weird, or a copy character?"

Ivan frowned, unable to understand.

But between the lines, you can find a possible fact!

The other party has a 33.3% probability of being weird!

There is a 50% probability that the other party is human!

There is a 66.7% chance that the opponent is a supernatural creature!

There is a 100% chance that the opponent is a specific NPC in the dungeon!

After thinking for a while, Ivan was more inclined to 100% specific NPCs, so he didn't think much about it, and directly ignited the Ferrari, started the engine, and then stepped on the accelerator, and the red Ferrari suddenly rushed out, and the surrounding picture was shattered, and then it became a hot desert road, "It's a little interesting, as soon as I got in the car and started the engine, I changed the scene nearby, and I met it for the first time!" ”

After reading it all, the audience couldn't help but ask curiously.

"The other party is wise, right?"

"Nonsense, there must be wisdom, the middle-aged hosts in white and black suits encountered by the Chosen One in the second level are all wise."

"What Ivan said is that there is no need to be entangled, he is a copy character!"

"That's kind of interesting, if it doesn't appear a little weird, I'm a little uncomfortable!"

"Upstairs, you have to change your mind!"

.......

Up to now, Jiang Zhe, Leon, and Ivan have successfully passed this level and embarked on the hot desert road, and are heading towards the third level.

At this time, Alice, Charlotte, and Monroe, who were playing with the host, also noticed the traps in the host's words one after another, and their answers were a little slower, and they needed to carefully determine the verbal traps in the host's words, and finally in the remaining 10 minutes, they ushered in three paradoxes!

10 minutes, for Alice, who is an actor, is really urgent, and for Charlotte and Monroe, it is a little simpler.

However, all three of them realized that for the first time, they could not choose the red door with Ferrari, otherwise they would lose!

Finally, in the penultimate two minutes, the three strong women completed the paradox in a tense manner.

Alice and Charlotte said in unison in different live broadcast rooms and at different times:

"I chose to change the door, the reason, the probability of me changing the door to get a Ferrari is 2/3, and the probability of not changing the door is 1/3!"

Without any accidents, the second daughter successfully challenged and won the Ferrari, and also entered the third level!

As a professor of philosophy, Monroe passed the level in the same way as Leon - using a philosophical way of thinking to pass the level.

Monroe sat on the Ferrari, looked at the stunned black suit host not far away, smiled, and subconsciously said with emotion:

"According to the calculations of Shao Yong, a philosopher of the Northern Song Dynasty of the Xia Kingdom, things in the world will completely reappear in 129,600 years, that is, in 129,600 years, you and I will still meet here, and I will still meet you. If it weren't for you, I wouldn't have been able to touch such an interesting three-door question, thank you! “

Hearing this, the expression on the face of the black-suited host on the stage not far away changed, and the Adam's apple shook for a moment, and the host was moved by Monroe, "No... No... You are welcome! ”

Seeing Monroe drive the Ferrari out of the scene, the black-suit host smiled, and then his mind moved, turning into brilliance and leaving the scene, arriving at the third level of the 'Court of Paradoxes'.

Alice breathed in the hot desert air and smiled: "It's such an interesting 'three-door problem', it almost misled me, but fortunately I focused on mathematics in college, otherwise I really couldn't pass." If I can get out alive, I must write a script based on the 'three problems' of the parallel world, I want to be a director, I want to be a star, I want to be a producer, I don't want the box office, I want to share my joy with everyone!! ”

Charlotte drove a Ferrari on the desert, the speed of the Mercedes stirred up the sand wind on both sides, and her fair face showed a thrilling and shocking wild laugh, "Wow hoo~ I didn't expect that I would be able to drive a Ferrari in my lifetime... Hey, shouldn't I be lamented by the three-door problem... Forget it, maybe I'll die at a certain level at some point, I want to drag race, my wife wants to drag race, my driving skills are not very good, if I overturn, I won't die, after all, the rules don't say [drag racing to death]! ”

As soon as she thought of this, Charlotte's sea-blue pupils suddenly widened, and the corners of her mouth couldn't help but outline.

The next moment, she stepped on the accelerator.

"Boom-" sounded.

In the blink of an eye, the red Ferrari shot out like an arrow, and the dust flew up!

Looking at the actions of the three people's personalities, the global audience smiled, but people knew in their hearts that how many people could really get out alive in the ending of the 13-star dungeon?

Forget it, don't think about it, cherish the present!

This is the current thought of the audience!

......

Like the Chosen One in other countries, there are more or less failures and successes.

Most of the success is achieved by women who are quite accomplished in mathematics and philosophy.

Most of the Chosen One, who entered the realm of life and death after failing the challenge and were given up by the country's axe, are mostly liberal arts and know nothing about science and philosophy!

20 minutes later, the number of live broadcast rooms in more than 40 countries dropped by 15 again, which means that 15 countries are experiencing strange invasions.

In the global picture, there are now 25 live broadcast rooms left!

Seeing this scene, the audience switched to the No. 1 live broadcast room in the first place: Xia Guo.

Because...

Jiang Zhe has already reached the third level first!
