A disc-shaped object is lying upright in the mall, emitting soft and extravagant gold.
The light flashed and twinkled, and Wang Yan heard the smell of wealth.
Take a closer look, it's actually a turntable?
Hey, what a fresh prop!
[Oufei turntable (primary)]
[use times: 1]
[selling price: 1 million]
[Note: there are always people who feel that they are full of black meat. Don't give me a shot. Spend money on it! ]
Oh, I'll go!
Broken props are provocative, huh?
Wang Yan was a little unconvinced. He rolled his arm net sleeve and wanted to try it right away.
However, after reading the details It's wilting.
The turntable has a total of 10 grids, which are equally divided, and each grid accounts for 10% of the total.
There are four colors: white, green, blue and gold.
White is three, there are no prizes, but there are four words written, not a relatively polite "thank you for your patronage", but a sharp taunt - non chieftain rolling thick!
Obviously, the turntable has a 30% chance of losing money.
One more level, it's four green.
Each of the four prizes is different. Wang Yan first focuses on the price. The cheapest one is priced at 200000 yuan, and the most expensive one is sold at 800000.
That is to say, there is a 40% probability of blood loss of 200000-800000.
There are only two blue prizes, which cost 1.5 million and 2 million respectively.
In the end, there is a golden reward at the price of Five million!
Therefore, the result is obvious. Wang Yan can easily find out that he has 40% probability of small loss, 30% probability of losing money, 20% probability of making small profit and 10% probability of making big profit.
"Hooligan!"
The rich and noble brother was very angry, and was extremely dissatisfied with the black heart system.
If the probability of winning or losing is 50% to 50%, at least it can be regarded as a fair bet. It's really not true. It's no wonder that you're having a bad time bumping into the wall.
What the hell is this now?
70% probability of loss!
Silly beep to play with you!
After Wang Yan finished scolding, he took a glance at the cash in the panel, removed the 100000 that was paid for Chen Xiang, and there was 1.62 million that could be used at any time, and then gnawed his teeth fiercely.
"Pay!"
Surplus salary: 620000.
System experience: 719 / 2500.
Holding items: children of destiny, extraordinary force Geka, double flavor food card, real heart card after drinking, Oufei turntable (primary)
sleeping trough?!
Don't you say you don't gamble?
Mr. Wang, why are you so inflated?!
Wang Yan is not really inflated.
The result of primary school mathematics is blood loss, so you are primary school students.
Elder brother but 79 intelligence, outstanding in excellent!
And just learned the basis of statistics, it is really not in vain.
In probability theory and statistics, there is a specific concept called "mathematical expectation value", which is translated as "mathematical expectation value".
Leaving aside the definition, let's take the simplest example - all casinos, designed gambling projects, use this concept.
For example, Las Vegas roulette, which is similar to the European and African turntable, has a total of 38 squares, corresponding to 38 numbers. If you bet a single number for $1, you can get 35 dollars.
The result is -0.0526.
That is, on average, for every dollar a gambler places, he loses 5.26 cents to the casino.
This is a fixed probability, as long as the number of samples is large enough (enough gamblers), it is sure to make a profit.
Therefore, regular casinos don't have to spend thousands of dollars. They can earn money every day.
make complaints about the mathematical expectation of the European turntable after the completion of the system's black heart.
(400 × 10%) + (100 × 10%) + (50 × 10%) - (80 × 10%) - (60 × 10%) - (40 × 10%) - (20 × 10%) - (100 × 30%) = 50000
the mathematical expectation is positive.
This means that as long as you play enough times, on average, you can earn 50000 per play.
Stupid beers don't bet!
Not only to gamble, but also to gamble until the end of time!
Mentally retarded system you give me out, after every week for brother refresh a turntable, you dare not?!
System: O ((⊙)) O.
if the system has wisdom, it will swear.
Every day I give you so much money to let you go out to surf, you don't drive well, just learn those messy things!
Take the mathematical knowledge pit system, what kind of God are you!(╯`) ╯┴┴
fall!
……
However, the system is not intelligent, so the room is very quiet, only Wang Yan's excited breath.
"Start the lottery!"
The turntable goes on and on, and the pointer goes through white, blue, green, gold
Finally, it passes through another white area by a millimetre difference, and finally stops in the green area.
Ma Dan!
Lost!
However, Wang Yan only complained, but did not have any regrets.
It's impossible to make money every time you play with probability. However, as long as the system does not change its design and the mathematical expectation is always positive, Wang Yan will dare to play with ya until the sea is dry and the rocks are rotten.
Shenhao, who knows mathematics, is so confident!
Take out the final reward, Wang Yan looked, happy.
Ah?!
It seems that there is nothing to lose?
The prize is a skill book.
[hard pen calligraphy (Master level regular script)]
[upgrade your hard pen writing level to master level, only one step away from the master]
[price: 400000]
[Note: only in block letters. Real, Xing, Li, Cao, Zhuan and other calligraphy styles need to be learned by themselves]
master level regular script, is it useful?
It's not much use.
In modern society, there are fewer and fewer places to start writing, not to mention Wang Yan, who is such a God. There is absolutely no chance to write something.
But another question: is it worth it?
It's worth it!
How can it not be worth a million dollars to buy a master level skill?
As a God, you can never be short of money.
Therefore, anything that can improve their own quality, as long as it can be exchanged with money, is worth it.
Wang Yanmei Zizi used up the skill book. In an instant, he had a lot of knowledge in his mind.
There are paper and pen on the desk. Wang Yan sat down with great interest and wrote down four names.
Wang Dayuan, Wang Xiufang, Wang Yan, Liu Li.
The iron bone and silver hook are dignified.
Wang Yan was overjoyed. After thinking about it, he added a fifth name.
He Meng.
Slightly deformed, it is no longer a regular block letter, but it has more flavor than the beginning.
Because, more of their own style.
79 intelligence, understanding is so strong.
In fact, writing has always been Wang Yan's short board. Although it is not as low as the level of primary school students, it is absolutely not good-looking. It can be said that the structure has no structure, and the line has no line.
However, as a normal aesthetic student, Wang Yan knows what kind of words are good-looking and likes to read them.
The reason why Wang Yan secretly falls in love with he Meng is not only because of her beautiful appearance. When she was higher than the blackboard newspaper, her elegant blackboard writing skills were amazing to all the boys in the class.
Later, he Meng's academic performance gradually declined, and the eldest lady's temper became more and more prosperous. However, the handwriting was always the beauty in Wang Yan's memory.
Don't exaggerate.
When a girl is beautiful, but also with some elegant attributes, that kind of lethality, absolutely penetrating damage.
Now Wang Yan and Wang Hao have no love for he Meng.
However, after getting master level hard pen calligraphy, I can't help but think of her, and think of her little feelings.
In a month, my friend, now his appearance is soaring, his height is soaring, and his body is smooth. Even his calligraphy has surpassed you. It's like a dream
Ha ha, what a wonderful dream!
Wang Yan got up, put his first calligraphy work into the paper shredder and stretched himself freely.
I don't know if I'm a guest in my dream!
Wait
It's not right to chant ambition with poetry.
It can be changed into another two sentences -
I wish I could see the flowers of Chang'an as soon as the song is over!
