Crowman fell silent, and Lin Yu was slightly moved.
This "hint," combined with the layout of the room and the information he had obtained from the first question...
All of it immediately reminded Lin Yu of a very classic "probability theory problem."
Sure enough.
Crowman spoke again.
"Caw caw, congratulations to you all. You've arrived at the 'choice' question in the first room."
"Caw caw, as you can see, there are doors of different colors in this room—but only one door leads to the next room."
"Caw caw, as for the other doors... you already know where they lead. They lead to the 'endless' void. Once you fall in, there's only death!"
"Caw, all of your answers must still be the same. You must choose the same door, or I won't take you through it!"
"So, everyone, please... make your 'choice' and tell me the color of the door you want to choose!"
As Crowman spoke, Lin Yu immediately understood.
Bu Wang spoke at the same time. "This is the Monty Hall Paradox... also known as the Three Doors Problem!"
Bu Wang spoke softly, and Lin Yu looked at her in surprise.
"You actually know this?"
Bu Wang looked at Lin Yu, her expression turning displeased. "It's not some profound or cutting-edge theory... Isn't it perfectly normal for me to know it?"
"Although I was wrong to steal your bicycle, you can't question my knowledge, too!"
Lin Yu was speechless.
He had indeed subconsciously looked down on Bu Wang's education—after all, this girl's class was "thief."
Considering that the class each person awakened was most likely closely related to their life, and that Lin Yu had also encountered a "thief" in the first Instance,
Lin Yu had almost subconsciously assumed that, like Yao Zhengye, this girl was a professional thief!
And a professional thief of this age definitely wouldn't have gone to school.
Knowing the elementary-school mathematics from earlier was one thing...
But the Three Doors Problem was part of probability theory. Although it was very basic...
It wasn't all that widely known.
Lin Yu looked at April, Number Eight, and Uncle Tie.
The two college students and the white-helmeted construction-site supervisor had clearly never heard of the theory.
They all looked at Lin Yu and Bu Wang in confusion.
"What's the Three Doors Problem?"
Bu Wang glared angrily at Lin Yu. "Then Nine Waters, you explain it!"
The water level was rising higher and higher. Lin Yu had no time to argue with Bu Wang, so he began giving a simple explanation of the Three Doors Problem.
"This problem came from a television game show, and it's exactly the same as our current situation."
"Simply put, someone has to choose one of three doors. Only one contains a prize and is the correct door. The other two are wrong."
"After the person chooses one, the door won't open immediately. The host will open one of the other wrong doors, then ask whether he wants to switch his 'door.' The point of contention is whether switching doors increases the probability of choosing the correct one."
Because time was tight, Lin Yu didn't give them time to think it over themselves.
"I'll give you the conclusion directly. The answer is yes—if you don't switch, your chance of winning is one-third. But if you switch, it's two-thirds!"
This counterintuitive conclusion immediately drew doubts from Uncle Tie, April, and Number Eight.
"You mean we choose a door first, then after Crowman opens one, we immediately switch to another?"
Uncle Tie spoke in disbelief.
"That's right," Bu Wang said urgently. "This is a probability theory problem. The mathematical community settled it long ago. If you want to know why, Nine Waters and I can explain it to you after we're safe in the next room!"
"For now... just do it this way!"
The water level was rising higher and higher. Bu Wang could no longer touch the ground at all.
She paddled constantly through the water, and her voice naturally carried a trace of anxiety.
"All right, I'll trust you for now," Uncle Tie said through gritted teeth. "We just choose any door first, right? Then we'll choose red!"
"Fine, red it is!"
April and Number Eight quickly agreed.
The five of them chose red together, and Crowman began laughing.
"Caw caw, you chose red first... very good. Now I'll give you your 'hint'!"
Crowman then flapped his wings, and the yellow door opposite the red door opened.
"Splash—"
Beyond the yellow door was a pitch-black void. Water surged out from inside, and the powerful current pushed them toward the yellow door.
Although the water level began to drop, letting the five players breathe a sigh of relief, they soon realized...
The current was also dangerously strong!
"What kind of lousy reward is this!"
Number Eight cursed as he hurriedly wrapped his arms around April to keep his girlfriend from being swept away.
Nearby, Uncle Tie paddled against the current with both hands, assuming a horse stance to steady himself.
Bu Wang, who already couldn't touch the ground at all, completely lost her balance this time.
"Help!"
She desperately paddled through the water, watching as she was about to be swept out.
When she was less than half a meter from the yellow door,
Lin Yu, as steady as Mount Tai in the current, sighed. Using the Soldier's fivefold physical ability, he easily walked over in two steps, grabbed Bu Wang by the collar of her windbreaker, and carried her back to the center of the room.
Still shaken, Bu Wang looked at Lin Yu and said, "Thank you... thank you, Nine Waters."
"You're truly magnanimous. Even though you kept pulling a gun on me and scaring me just now, in the end, you were still the one who saved my life..."
Bu Wang gasped for breath as she spoke.
Lin Yu helplessly flicked her on the forehead. "I just felt that you didn't deserve to die!"
Although stealing his bicycle had been despicable, Lin Yu didn't think she deserved to die.
After participating in the Death game, Lin Yu's mindset had changed somewhat. When necessary, he could absolutely kill someone.
But that didn't mean he had become a cold-blooded psychopath who would stand by and watch someone die or kill people at random.
Although Bu Wang had some conflict with him, she definitely hadn't reached the point where he needed to kill her.
What was more...
Lin Yu had vaguely realized that although Bu Wang's class was "thief," she might well be the most useful teammate in this Deadly Q&A game!
After all, Bu Wang seemed very clever.
As the yellow door opened, the rate at which water flowed in fell far below the rate at which it drained. The water level in the room soon dropped to below everyone's waists.
The current also slowed considerably. Lin Yu released Bu Wang's collar, but the girl still seemed shaken and continued clinging to his arm.
"This little bit of water can't sweep you away anymore!"
Lin Yu spoke helplessly.
"No way. Besides, that pair of dogs over there still hasn't let go of each other!"
Bu Wang pointed at Number Eight, who was still embracing April.
Lin Yu was speechless. "You know they're a couple, too... We don't even know each other."
"Then there's nothing wrong with you and me becoming a couple, either," Bu Wang said shamelessly. "Brother Nine Waters, I like you!"
"Get lost. Stop fooling around."
Lin Yu spoke helplessly, but ultimately didn't force Bu Wang to let go.
The other three heard their conversation.
April nudged Number Eight, and Number Eight awkwardly released her.
"The current really isn't a problem anymore."
Uncle Tie, standing alone in his horse stance, suddenly sighed.
"Young people have it good... But even though the water level has gone down, we should hurry and switch doors!"
"What's left now is the blue door, right?"
