Chapter 266 Obtaining [Undead]
Liu Mao continued to press the button to get the prompt.
“To get the prompt for the second time, you need to invest two [Memories].”
A pleasant female voice sounded.
Same as what Ke Lan said, every time you get a hint, the cost will double compared to the last time.
According to this ratio, no matter how much [memory] you have in your hand, it will not be enough to create it.
After investing two pieces of [Memory], Liu Mao got the second prompt.
“There is at least one ‘trap box’ in the first row of boxes.”
Liu Mao wrote down this tip.
"There are four boxes in the first row, and the prompt says that there is at least one 'trap box' in the four boxes, at least one. It could also be two, three, or even four. This prompt is too It’s too general.”
Liu Mao was a little helpless.
He felt that if he was allowed to guess randomly, he could guess that there might be a 'trap box' in the first row.
So he immediately chose to press the button to get the prompt again.
This time, four [Memories] need to be complained.
Including the previous investment, six [Memories] have been invested before finding which one is the ‘Grand Prize Box’.
This game is obviously very well designed.
Liu Mao was reminded of something.
Lottery.
He remembered that there was a time in the past when he liked to buy lottery tickets.
And I was very obsessed with it. I had to buy every issue. If I missed buying one issue, I felt like I would miss out on the millions and millions of grand prizes.
It is also necessary to study probability, and as long as you continue to invest, you can increase the possibility of winning from a certain probability.
However, Liu Maozai compared it carefully and found that these two things have their own advantages and disadvantages. One costs money but not life; the other costs both money and life.
The current box guessing game and The lottery is very similar. You can invest low and use only one card to gain luck. You can also invest heavily, but only If you think about it for a moment, you will know that a big investment is almost like a bottomless pit, because getting the hint for the fourth time will consume eight [memory] cards, the fifth time will be 16 cards, and the sixth time will be 32 cards. , the seventh time is directly sixty-four
No matter how many [memories] you have, you can finish them in this game.
What is certain is that the 'hint' cannot tell you the location of the 'big prize'. Even if you get a relatively accurate location, it is estimated that you will get about the eighth hint, accumulating hundreds of [memory] Just to clear a game?
No matter how stupid a fool is, he won't play like this.
Liu Mao has considered this issue in his mind, so he thinks that three times of 'getting prompts' is acceptable, but the fourth time is not worthwhile.
The third prompt is: there is at least one 'empty box' in the second row of boxes.
“I finally understand. All the prompts are just Tai Chi. It’s impossible to tell me the location of the grand prize box clearly. But this is normal. I can’t continue to invest, because nothing unexpected happens. Even if it is the fourth prompt, it is impossible to give any too important hints, but it consumes too much [memory]."
Liu Mao thought about it carefully and found that if the first three prompts were combined. Analyzing them together is actually helpful.
"The grand prize is not in the last row, then it can only be in the first two rows. There are 4 boxes in the first row and 3 boxes in the second row; there is at least one 'trap box' in the first row and at least one in the second row. 'Empty box'. So if I want to try, I should start from the second row. There are only 3 boxes in the second row, and I can already determine that there is at least one 'empty box', then So according to the worst case scenario, the grand prize is not in the second row, and the other two boxes are 'trap boxes', then the probability of me drawing an 'empty box' is also one-third. On the other hand, as long as it is not the worst case scenario , even the grand prize box is in the second row, so the probability of me drawing the safe box is two-thirds."
Liu Mao took a deep breath.
He decided to try his luck.
He stretched out his hand to get the box, but after thinking about it, he retracted.
“Wait a minute, I have to think about it, what happens after I take a certain box in the second row? Either I get the grand prize, or I am unlucky enough to get the trap box, let’s see what happens. Or, get the empty box. In fact, except for getting the trap box, the remaining two possibilities are neither Very good, needless to say about the grand prize, just clear the level directly. If it is an empty box, I might be able to use the 'Exclude Empty Box' button, then the excluded empty box may appear in any of the three rows. The third row Calculating my misfortune, the second row and the first row are both valuable to me.”
Liu Mao wiped the sweat from his forehead.
He feels that this game is more torturous than fighting with people directly. He prefers simpler games, for example, instead of guessing boxes, it is to move boxes. It is cheaper to move hundreds of boxes than this. Heart.
At least, my heart is not tired.
Liu Mao didn’t have the energy to think about more.
"Let's follow this idea first." Liu Mao took a deep breath, looked at the three boxes in the middle, and picked up the middle box based entirely on his feeling.
The next moment, the box bursts open, revealing its contents.
is a note.
It says 'empty box'.
"Huh~" Liu Mao let out a long breath, but there was even more sweat on his forehead.
Then he pressed the 'Exclude Empty Box' button. Of course, to trigger this button, he also had to pay a [Memory].
The next moment, the box on the left side of the third row was shattered, and the note inside said 'empty box'. Seeing this, Liu Mao couldn't help but curse.
He rarely swears, but this time he couldn't help it.
“It’s for nothing!” Not only was his forehead sweating, his heartbeat was also starting to speed up, and his palms were all sweaty.
To be honest, this thing feels more exciting than fighting against a ghost.
Liu Mao stretched out his hand and wiped it on his body, wiping the sweat from his palms, then wiped his forehead with his sleeve, and finally rubbed his face again.
"I think about it again. I have used [memory] a lot. In addition to making sure that the 'big prize box' is not in the third row, I also made sure of two other things. There are at least four boxes in the first row. I touched an 'empty box' in the second row of a 'trap box', and also eliminated an 'empty box' in the third row. This is equivalent to eliminating at least three boxes. Son, the probability of winning the grand prize now is one-sixth. No, no, I should change my thinking. If it were Luo Xi, he would definitely change his thinking. He would definitely analyze the second row and the third row separately. It's just a hypothesis, Luo Xi likes hypotheses the most."
Liu Mao looked at the two remaining boxes in the second row and the four boxes in the first row.
“I also assume that the big prize is in the second row, then I continue to touch the second row, and the probability of getting the big prize is one-half; conversely, the probability of getting the big prize in the first row is one-quarter, and it has been I know there is at least one trap box in the first row, and there must be a 'death box' in the existing trap box. Hey, wait a minute."
Liu Mao suddenly realized something.
"There is only one death box. In other words, the probability of getting the big prize is the same as getting the chance of death. Then my idea should be to stop staring at the 'big prize' and figure out the 'death box'." location, and then choose the one with the smallest probability of the existence of the death box and the highest probability of the existence of the 'big prize box'."
Liu Mao doesn't know whether this idea is correct or not. Anyway, he has nothing better. method.
“Now the death box may exist in one of two places in the third row, one of two in the second row, one of four in the first row; and the grand prize exists in one of two places in the second row, one in the first row Choose one out of four, that is to say, the probability of me getting the big prize and getting death in the second row is one. Like this. In addition, I only used it once to eliminate the empty boxes. The second time I used it, I only needed two [Memories]."
Thinking of this, Liu Mao did not hesitate and stared at the four people in the first row. box, and then reached out very decisively to pick up the first box in the first row.
The note inside said ‘broken finger’.
It's a trap box.
But when he saw this note, Liu Mao smiled. Even when one of his hands was pinched by a machine, and then his little finger was cut off by a sharp electric saw, he just gritted his teeth and did not say anything. A little sound.
"Luckily, it's not death." Liu Mao quickly wrapped the wound with the hemostatic cotton and bandages placed nearby.
It's just a broken finger, he doesn't care.
"In this way, the probability of selecting the grand prize box in the first row has increased. Then, I choose to 'exclude the empty boxes' again." Liu Mao knew that these two [memories] were his The last card of the round is paid.
He will no longer use the 'Get Tips' or 'Exclude Empty Chests' buttons.
Crack~
The third box in the first row was broken. It was an empty box.
This result is not what Liu Mao wants to see, but there is nothing he can do about it. The situation is just like this, and he has to accept it, good or bad.
And he suspected that there were no empty boxes now.
Among the remaining four boxes, there is a grand prize box, and the remaining three boxes are all trap boxes. There is a death in the trap box, and the big prize is either in the second row or in the first row, and the same is true for death.
The probability is 1/2.
"No, in this case, the probability of touching the big prize box is still one-quarter. I need another prompt to exclude the second row or the first row." Liu Mao replied carefully at this time. After taking stock, he discovered a reality.
Then he was mistaken.
The idea was wrong. He made wrong choices in many places during the whole process.
Because of the final result, he did not really increase the probability of winning the jackpot, and at the same time, the price he paid was also very high.
The more I think about it, the more anxious and irritable I become, filled with anger towards myself.
Liu Mao, who originally planned to make another purchase reminder, simply smiled.
He didn’t think about it or analyze it anymore, because he found that he was not born to do this.
"Four boxes, I can choose whatever I want." Liu Mao did not hesitate anymore and gave up thinking. He looked at the box on the left side of the second row and reached out to grab it.
The box breaks open.
The note inside was revealed.
It says 'Grand Prize'.
"???" Liu Mao was stunned for a moment, then smiled helplessly: "If I had known earlier, I would have chosen randomly, what a waste."
"Congratulations on winning the grand prize box , now you can choose a clearance reward among five boxes. The reward cards and quantity in each box are different. Of course, you can also choose to spend 2 [Memory] to exclude a box with the least number of cards."< br>
"Get the hell out of here!" Liu Mao cursed, and at the same time grabbed someone randomly based on his feeling.
Bang!
The box shattered and a stack of cards was immediately revealed. There were five cards in total. Except for two [memory] cards, the remaining three were functional cards. The most important thing is that these three functional cards Among the cards, there is a [Undead].
