my stealth fighter

Chapter 698 25%
Marikina used it 3000 times, and increased the coin toss game, which should have an infinite tendency to a 50% correct rate, to a 60% winning rate. Although coin tossing is simple, tossing thousands of times or tens of thousands of times is harmful to mental and physical strength. Among other things, let ordinary people try to toss coins 3000 times?I'm afraid my thumb will be bruised.

For the subjects, if it is the kind of self-defeating guessing method, it will be fine, but if they take every guess seriously, it will be an extreme mental torture, no less than doing math problems for several hours in a row.

Although the math problems are complex and difficult, guessing coins seems simple and easy, but many people underestimate the mental torture of "infinite repetition", just like the kind of volunteers who are locked in a device without any entertainment, no time display, and cannot take a bath , The challenge game in the room with irregular meals may seem simple, but in fact few people can stay in the room for a full week.

However, no matter whether it was the continuous guessing and wrong guessing at the beginning, or the continuous upward trend of the current accuracy rate curve, there was no way to change the expressions on the faces of the two officers and General Pasinkova, as if they were wearing a dull mask. .

5000th time.

green counter = 3404
red counter = 1596
As the officer tossed the coin high and down for the 5001st time, the silver arc suddenly seemed to learn the technique of splitting in Marikina's eyes, changing from one to three, and the three arcs were still dancing with each other. entanglement.

Marikina was dizzy, swayed, and fell under the chair.

The petrified General Pasinkova took a step forward and tapped her on the shoulder, instead of letting her fall to the ground, she lay powerlessly on the table.

She struggled to straighten up and continue guessing, but she was dripping with cold sweat and had already collapsed.

The officer briefly glanced at the counter and calculated that the current correct rate is 68%, which is more than 2/3.

"That's the end of today's test," the officer who tossed the coin announced.

"I... I can still guess... it hasn't reached 1 times..." Marikina said weakly.

"You don't need to guess anymore today, you can go back and rest." The officer stood up and ended the recording, and uploaded the video file to the server.

"Did I pass the test?" Marikina asked nervously.

"You passed today's test. There is a new test tomorrow, so go back and have a good rest," the officer said.

Marikina was a little relieved, at least she passed today safely, not knowing what kind of test was waiting for her tomorrow.

During the test, General Pasinkova did not interfere in any way, nor did she raise any objections to the test results. After the officer announced that today's test was over, she turned and left the compartment, her expression still unchanged.

Marikina was very disappointed. She thought that if she passed the test, the general would at least show an encouraging smile, but since she had made up her mind to change her fate, she would never give up unless she was declared ineligible.

Before leaving the cubicle, she glanced at the counter. In the second half of the test, she didn't look at it again, because she didn't want to be distracted and her mentality was not affected. Although she vaguely felt that her correct rate was getting higher and higher, But how high it was, she didn't know until she looked at the counter now.

There is actually a 2/3 correct rate?

This result was like a shot in the arm, which revived her who was already exhausted, her weak confidence was also greatly enhanced, and she was even a little complacent, shouldn't she be happy?This is a game that should hover around 50% correct rate, but this is a good result, why didn't the general show any signs of it?
In fact, this result is not bad in the eyes of the general and the two officers, but it is only good, and it is only a degree of passing in advance.

As long as there are enough tests, the correct rate should approach 50% infinitely.

How much is 1 times enough?Enough, but not enough.

But as long as there are enough testers, all kinds of monsters and ghosts may appear.

How much is 1 people enough?Enough, but not enough. After all, there is a problem of "probability". Even if you give the keyboard to countless monkeys to type, one monkey may type the complete works of Shakespeare.

They have seen amazing scores of more than 80% correct in the coin toss test, but then failed in the next day's test, because the coin toss alone cannot prove whether the subject is gifted or lucky. of favor.

the next day.

General Pasinkova reappeared in the same compartment.

Marikina was already sitting in the same position as yesterday, when the two officers were setting up the camera, the general did not interfere with them, and stood watching from the corner.

Today Marikina's complexion is slightly better than yesterday. She tried her best to smile and nodded to the general, but the general didn't turn a blind eye and didn't respond indifferently.

After the camera started recording, the two officers returned to their seats, and the officer who tossed the coin said to the camera:
"Subject: Darya Marikina."

"Test item: Telepathy."

"Test Sequence: Item [-]."

With yesterday's experience, Marikina probably already knew what she was going to face. Although she was inevitably nervous, she was already mentally prepared to succeed if she didn't succeed.

The officer who flipped the coin did not take out the coin today, but took out four playing cards from the pocket of the white coat, face up, and placed them side by side on the table, which are:
Heart A, Diamond A, Spade A, Club A.

"I will randomly draw one of the four poker cards and put it on the table with its back side up. You can tell its suit. The number of tests starts from 1000. Each time you have 5 seconds to say the answer, the timeout is wrong."

That was all the rules, as simple as flipping a coin, and the officer explained it in just one sentence.

"Testing begins."

When the officer spoke, he had already put away the four playing cards, took them under the table, shuffled them briefly with both hands, and then drew a card and put it on the table with its back facing up.

Guessing flower cards is very similar to guessing coins yesterday. Marikina has already understood the rules. She stared at the back of the playing cards, not expecting any hidden marks on the back. After a moment of hesitation, she said, "Ace of Hearts."

The officer turned over the playing cards, and it was the ace of clubs.

Another officer presses the red counter, and the number of errors becomes 1.

After guessing a few times and paying attention to the back of the playing cards, Marikina knew that just like yesterday, this was just a pure guessing game, without any tricks and the possibility of cheating.

In fact, even the officer in charge of dealing the cards didn't know the suit of the cards before she opened the cards. Her hands under the table shuffled the cards completely randomly, and she focused on Marikina On his face, he deliberately did not feel the process of shuffling the cards.

If the result of coin tossing yesterday should be infinitely close to 50%, then the result of guessing flower cards today should be infinitely close to 25%, but in fact, the correct rate of the subjects is generally less than 25%, basically only 15% to 20%. %, because in the guessing process, the subject will inevitably be affected by psychological factors. The last time the square A was guessed correctly, the next time it will often be guessed from the other three, but each guess is independent. One time it was the A of squares, and the next time it might be the A of squares. There were even cases where the same card appeared more than a dozen times in a row, and this often caused the subjects to have a nervous breakdown.

Tossing a coin more than ten times in a row leads to heads or tails. Most people feel helpless and ridiculous, but it is acceptable. However, if the same card appears more than ten times in a row, people will inevitably have thoughts in their hearts, such as suspecting that the tester is It is not deliberate deceit, and may even become violent or aggressive under emotional excitement, and such subjects will be directly judged as failures.

Even if the subject has understood the probability problem and knows that each guessing process is independent, but knowing it belongs to knowing, just knowing, can the thoughts in the mind be unaffected?
It can be said that no matter guessing coins or flower cards, unless the subject doesn't care about the outcome at all, just like gambling with other people's money in a casino, it will have a negative impact on the mental health of the subject, and may even cause Whenever they recalled this incident throughout the rest of their lives, they would be filled with regrets, and only a very small number of people could survive it firmly.

100th time.

green counter = 18
red counter = 82
The correct rate is 18%.

Marikina seemed to be dazed, she held her head in her hands, pinched her scalp with her fingernails, her eyes were almost cross-eyed, staring desperately at the back of the playing cards on the table.

It was not until 100 times that she managed to adjust her mentality and pull herself back from the abyss of guessing and making mistakes. The method was to not pay attention to the green counter, not to pay attention to General Pasinkova, not to pay attention to all foreign objects, and to forget Wherever you are, just focus on the playing card itself, and imagine the suit on the front of the playing card in your mind.

Whether it is yesterday or today, the test not only challenges the talents of the subjects, but also the spirit and willpower of the subjects.

It was no accident that Marikina appeared in this compartment. After the smuggler's smuggling boat was intercepted, she and other school-age girls were taken to a nearby annex building, where they lived collectively for a short period of time, that is, the 15 days before yesterday. God, they have nothing special to do, just eat, sleep and play games they are interested in every day.

The games for them to choose include intellectual games, competitive games, survival games, fighting games, board games, etc. During their games, they have been secretly observed. Talent will be taken to the No. 43 Independent Scientific Experiment Station affiliated to the Strategic Rocket Force for testing.

Marikina was noticed for the first time during the game of drawing cards. When she played with the girls, she was able to avoid the cards most of the time and became the final winner. When you smile.

The testers asked them to wear cute masks to draw jokers, with only their eyes exposed. They thought it was for fun, but in fact it was to prevent them from winning by observing words and expressions, which would lose the meaning of the game.
