The words are divided into two parts. On one side, Feng Yan found the clown boots and prepared to go to the back of the stage to explore in depth. On the other side, the mountain ghost was not so relaxed. She now urgently needs to unlock consumables because the [Witch Doctor Bacteria] on her body is... Time waits for no one. The red line at this moment has climbed to her elbow and will soon reach her upper arm. Once it reaches her shoulder, she will die immediately, while Feng Yan wins without a fight.
This was the price she paid for unlocking the weapon first and rushing to kill Feng Yan. If she seizes the opportunity and kills Feng Yan, the game will be over. Naturally, she does not need to pay attention to this DEBUFF, but now that she has failed, she has to face It's an even more difficult dilemma - quickly eliminate this DEBUFF.
[Witch Doctor Bacteria] must be removed by cutting off the arm below the thin line. It is not impossible to cut, because fortunately, the mountain ghost also has a bottle of consumables that can instantly restore the severed limbs. As long as the red line reaches the shoulder position, Unlocking the consumable can cut off the arm, and then immediately restore it to completely remove the DEBUFF.
The mountain ghost walked toward the southwest and said: "Based on the plot of unlocking weapons, most of the plots of unlocking consumables will also be puzzle-solving."
Since he had stolen the information about the conversation between Feng Yan and the magician, and learned that the mission triggering mechanism would follow the player no matter how he went, the mountain ghost chose a random direction and left.
Xiao Qingyun was connected with the mountain ghost and knew her current mood, so he comforted her: "Don't be too anxious. Once the plot is triggered, we will calmly solve the puzzle step by step. Judging from the climbing time from the appearance of the red line to now, There are still at least 20 minutes to get to the shoulder, so as long as we don't get into trouble, that should be enough time."
Shangui breathed a sigh of relief and said, "Well, I believe in your strength."
While the two were switching personalities, they unknowingly reached the carousel venue.
The mountain ghost looked up at the carousel facility in front of him and said, "I have never seen such a big carousel before."
The carousel in front of you has 5 floors. There are 81 Trojan horses on the first floor, 27 Trojan horses on the second floor, 9 Trojan horses on the third floor, 3 Trojan horses on the fourth floor, and the last floor is the only one on the top floor. One of the Trojan horses is a pink unicorn, and on the top of the carousel stands a sign with the name of the Trojan horse device: Fright Trojan.
When I was hesitating whether to go in and explore, the system narration appeared.
[Welcome to the unique five-story carousel equipment 'Terror Trojan'. This equipment has a total of 121 Trojan horses. According to legend, there is an evil spirit sealed in each Trojan horse. At night, these sealed evil spirits will Emerging from the wooden horses, they will ride on their sealed wooden horses and let out lonely and painful groans]
[The side mission has been triggered: After entering the 'Terror Trojan' device, an evil spirit leader will appear on each floor. After successfully completing the tasks assigned by him, you can go up to the next floor, and so on until you land on the top floor]
[Completion reward: If you complete the side task before the opponent player, you will immediately gain the right to unlock consumables and immediately have the right to view the opponent's position for 10 minutes]
[Hidden reward: After successfully ascending to the fifth floor, immediately complete the side task and obtain the reward. If you choose to challenge the task of the Unicorn ** generation, you will obtain the hidden reward]
Feng Yan is a master of exploration, but Xiao Qingyun is not a mediocre person. Although Xiao Qingyun's B-level exploration level is lower than Feng Yan's A-level, she has stayed at B level for a while. In theory, she has already On the verge of breaking through the A-level exploration level, with just one step or a high-scoring performance highlight, you will be immediately promoted to A-level exploration after the copy is over.
Therefore, Xiao Qingyun also wanted to get all the rewards Feng Yan could think of for extorting money. As early as when she accepted the task, she had obtained the hidden reward of entering the dungeon in her own way. Ronald promised that as long as she could win the first place with Feng Yan, During the first fight, she saw off one of his legs and entered the second item unlocking stage, and there would be a hidden reward for her.
Feng Yan later learned about this and yelled at Ronald for an hour, saying that he acted one way on the outside and another on the other side, saying that he deliberately opened a back door for Xiao Qingyun and provided the convenience of unlocking weapons very quickly, in order to target and saw off himself. of a leg.
Ronald just folded his arms and listened for an hour. Later, Feng Yan got tired of scolding and began to reveal his true purpose-to order equipment and items as mental compensation.
Ronald in front of him took off the cotton in his ears and said, "I'm sorry, Brother Yan, I am Ronald's clone, Uncle McDonald of the Nepal branch. My nickname is Pan Rock."
Then Panshi succeeded in making Feng Yan gain nothing by relying on his strong endurance and interruption skills.
After the narration and side mission information were introduced, the originally colorful carousel with cheerful music immediately became dim, and the music became stuck. The atmosphere was extremely strange for a while, and the people who were originally empty were even more permeable. Each of the floating wooden horses now has a transparent ghost riding on it.
All of these ghosts looked ferocious with missing arms and legs. Looking at Xiao Qingyun, his legs felt a little weak.
Mountain Ghost: "Can you do it?" Just love it
Xiao Qingyun swallowed and nodded: "These ghosts are just there to enhance the atmosphere of this side mission. They will not cause any substantive attacks. Solving the puzzle is the main topic, so there should be no problem."
After entering the first floor of the Trojan of Fear, before Xiao Qingyun could turn around, the leader of the evil spirit from the first floor of the Trojan appeared.
"Hello my friend, I am the leader of the evil spirits on the first level of the Terror Trojan. My name is Ohm..." Ohm paused and said: "The incarnation of wisdom."
The Ohm in front of me is a short white man with yellow hair. He claims to be the embodiment of wisdom, which may mean that the essence is concentrated.
Xiao Qingyun said simply and clearly: "Please give me a question."
Ohm didn't talk nonsense. With a wave of his hand, three wooden doors appeared outside the panic Trojan. Ohm pointed at these three doors and said: "Two of these three doors are angels, and one door is devil. You choose one first." A door that thinks there is a demon inside.”
Xiao Qingyun whispered: "Is it a problem with the three gates?"
Then she randomly selected a door on the far left and said, "I choose this one."
Ohm snapped his fingers and ignored the door on the left that Xiao Qingyun picked. Instead, he opened the door in the middle, and an angel appeared inside.
"As you can see, there is an angel in the middle door, so please answer my question. What is the probability that you will choose a devil among the two doors on the left and right? Why?"
The mountain ghost said: "This is not simple. If we know that there is an angel in the middle door, then there is still one angel door and one devil door. The probability of selection is half and half and 50%!"
Ohm smiled: "Exploring the strong man, are you sure?"
Xiao Qingyun switched body control and said: "No, the probability of me selecting the devil at this moment is 33.3% for the left door and 66.6% for the right door. These two values are infinite looping decimals, only one decimal place is taken."
A weird smile appeared on Ohm's face: "It's interesting. It seems you have heard of the three-door question."
Xiao Qingyun said: "This is a typical three-door problem, with just slight changes, including the things behind the door and the rules."
Ohm nodded and said: "Hearing and understanding are two different things. Please explain in detail why this is such a probability."
Xiao Qingyun slightly raised the left corner of her mouth to create a shallow dimple on her face, which indicated that she had entered a state of reasoning.
"The three-door problem is a very counterintuitive paradox, just like Mount Gang... Just like I said wrongly just now, considering this matter from an ordinary person's perspective, there are only two doors left, one for demons and one for demons. Angel, the probability of choosing a devil is only 50%, no matter what, but many people have overlooked an important point. Whether it is just before the choice or after you open a door, the choice we make The foundation must be built on all three doors and the prerequisites you gave.”
After a pause, Xiao Qingyun said: "Everyone may have their own way of answering the three questions. I will only give the answers that I understand.
Since there are two angels and one devil among the three doors, the probability of me picking the angel is 66.6%, and the probability of picking the devil is 33.3%. And your initial request was to let me pick the door with the devil, then when I Based on this fact, when subjectively choosing Demon Gate, the probability is only 33.3%.
When I chose the door on the left based on this fact, you did not make it public and instead opened the middle door for me with an angel. At this time, you asked me again about the probability of selecting a devil between the left and right doors. I must still answer this question based on the probability of three doors.
After I picked the door on the left, you took the initiative to open the middle door to show the angel without telling me the facts. This reduced the original 66.6% probability of choosing the angel door to 33.3%, but the constant 100% probability cannot be shaken. Yes, this is one of them. The probability of me following your request to find the Devil's Door when you don't open the door is only 33.3%, which is also constant. This is the second one.
Based on the above two basic situations, there is no choice for the door in the middle at this moment, and the probability of participating in it can be automatically removed. The probability of the door on the left is fixed to 33.3% by your prerequisites, so the probability of the door on the right will naturally increase to 33.3%. 66.6% does not mean that the probability of picking a devil from the left and right doors is equal. "
