A disc-shaped object was lying upright in the mall, exuding a soft and luxurious golden light.
The light flashed and shone, and Wang Yan smelled the smell of getting rich.
If you look closely, it turns out to be a turntable
Hey, what a fresh prop!
[European and African Turntable (Elementary)]
[Number of uses: 1]
[Price: 1 million]
[Explanation: There are always people who think they are very European, but in fact they are all black. Stop talking nonsense and spend money to test it!]
Aiya, I go!
Broken props are quite provocative, huh
Wang Yan was a little unconvinced. He rolled up his arms and sleeves and wanted to try it right away.
However, when I read the specific details... I felt tired.
The turntable has a total of 10 grids, which are equally divided, and each grid occupies 10%.
There are four colors in total, namely white, green, blue and gold.
There are three white boxes, and there are no prizes inside, but there are four words written on them. It is not a relatively polite "Thank you for your patronage", but a biting sarcasm - Non-Chiefs, get lost!
Obviously, there is a 30% probability that the turntable will lose everything.
The next higher level is four squares of green.
The four prizes are different. Wang Yan's first concern is the price. The cheapest one is priced at 200,000 in the mall, and the most expensive one is priced at 800,000 in the mall.
This means that there is a 40% probability of losing 200,000 to 800,000 blood.
There are only two blue prizes, priced at 1.5 million and 2 million respectively.
The last square left is a golden reward, the price is... 5 million!
So the result is obvious. Wang Yan can calculate it with his elementary school mathematics knowledge. There is a 40% probability of a small loss, a 30% probability of losing all his money, a 20% probability of a small profit, and a 10% probability of a big profit.
"Stinking rogue!"
Brother Fugui was extremely angry and extremely dissatisfied with the black-hearted system.
If the probability of winning or losing is 50% vs. 50%, at least it can be considered a fair bet. If it is really not the case, then no one can blame you. You just hit the wall and accept your bad luck.
Now what the hell is this
70% probability of loss!
I'm stupid for playing with you!
After Wang Yan finished cursing, he took a look at the cash on the panel. After removing the 100,000 that was paid to Chen Xiang, there was still 1.62 million that could be used at any time, and then gritted his teeth.
"Payment!"
Remaining salary: 620,000.
System experience: 719/2500.
Items held: Son of Destiny, Extraordinary Style Card, Double Flavor Food Card, See Your Heart After Drinking Card, European and African Turntable (Elementary)
Damn it? !
Didn’t you say you won’t gamble
Mr. Wang, why are you so inflated? !
Wang Yan was really not inflated.
The result calculated by elementary school mathematics is blood loss, so you are only elementary school students, hehe.
My brother has an intelligence of 79, the best among the best!
And the basics of statistics I just learned are not for nothing.
In probability theory and statistics, there is a specific concept called "Mathematical expectation value", which is translated as "mathematical expectation value".
Putting aside the definition, let's take the simplest example - all casinos and designed gambling projects are applying this concept.
For example, the Las Vegas roulette, which is similar to the European and African roulette, has a total of 38 grids, corresponding to 38 numbers. You can bet a single number for 1 dollar, and you will get 35 dollars if you hit it.
Calculating the mathematical expectation, the result is -0.0526.
That is, on average, gamblers lose 5.26 cents to the casino for every dollar they bet.
This is a fixed probability. As long as the sample size is large enough (there are enough gamblers), you will definitely make money without losing money.
Therefore, regular casinos do not need to spend thousands, they can make a lot of money every day by recruiting a wide range of customers.
After Wang Yan complained about the evil heart of the system, he instantly calculated the mathematical expected value of the European and African turntable.
(400×10%)+(100×10%)+(50×10%)-(80×10%)-(60×10%)-(40×10%)-(20×10%)-( 100×30%)=50,000
The mathematical expectation is positive.
This means that as long as you play enough times, you can earn 50,000 on average every time you play.
You'd be stupid not to gamble!
Not only do you have to gamble, but you also have to gamble until the end of time!
Please come out of the retarded system and refresh a carousel for me every week from now on. Do you dare? !
System: o((⊙﹏⊙))o.
If the system is intelligent, it will definitely scold you.
I give you so much money every day to go out and have fun. If you don't drive a car and pick up girls, you will learn all those messy things!
You use your mathematical knowledge to cheat the system, what kind of genius are you
(╯‵□′)╯︵┴─┴
fall!
…
However, the system was not intelligent, so the room was quiet except for Wang Yan's excited breathing.
"Start the lottery!"
The turntable turns and turns, and the pointer passes through white, blue, green, gold...
In the end, it passed through another white area with a slight difference, and finally stopped in the green area.
Damn it!
loss!
However, Wang Yan only complained without any regrets.
It is impossible to make money every time by playing with probability, but as long as the system design does not change and the mathematical expectation value remains positive, Wang Yan will dare to play with Ya until the end of the world.
Shenhao who understands mathematics is so confident!
Wang Yan took out the final reward and was happy when he saw it.
Eh? !
It doesn’t seem like you’re losing anything
The prize is a skill book.
[Hard-pen calligraphy (master-level block letters)]
[Upgrade your hard-pen writing skills to the master level, and you are only one step away from becoming a master]
[Price: 400,000]
[Note: Only in block letters. You need to learn calligraphy styles such as Zhen, Xing, Li, Cao, and Zhuan by yourself]
Master-level regular script, is it useful
Not much use.
In modern society, there are fewer and fewer places to write, let alone a powerful person like Wang Yan, who definitely doesn't have many opportunities to write something by hand.
But let’s change the question: Is it worth it
It’s so worth it!
How could it not be worth spending 1 million to buy a master-level skill
As a powerful person, you will never be short of money.
Therefore, anything that can improve one's own quality is worth it as long as it can be exchanged for money.
Wang Yan happily used the skill book, and in an instant, a vast amount of knowledge poured into his mind.
There was paper and pen on the desk. Wang Yan sat down happily, pondered for a moment, and wrote down four names.
Wang Dayuan, Wang Xiufang, Wang Yan, Liu Li.
Iron bones and silver hooks, upright and dignified.
Wang Yan was overjoyed. After thinking about it, he added a fifth name.
He Meng.
It's slightly deformed, no longer in regular block letters, but it's more flavorful than before.
Because, have more of your own style.
The intelligence and understanding of 79 is so strong.
In fact, writing has always been Wang Yan's shortcoming. Although it is not as low as a crooked elementary school student, it is definitely not good-looking. It can be said that he wants structure without structure, and lines without lines.
However, as a student with normal aesthetics, Wang Yan knows very well what kind of characters look good, and he likes to read them.
The reason why Wang Yan has a crush on He Meng is not only because she is beautiful. When the blackboard paper was published in the first year of high school, her beautiful handwriting on the blackboard was astonishing 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 exuberant, but those words were always beautiful in Wang Yan's memory.
Don't think it's an exaggeration.
When a girl is both beautiful and possesses certain elegant attributes, her lethality is definitely penetrating damage.
Wang Yan and Wang Hao now have no feelings for He Meng.
However, after suddenly getting master-level hard-pen calligraphy, I couldn't help but think of her and the little feelings I had.
In one month, my appearance, height, and figure have soared. Even my calligraphy has surpassed yours. It’s like a dream...
Haha, what a cool dream!
Wang Yan stood up, stuffed the first calligraphy work in his life into the shredder, and stretched himself happily.
If you don’t know that you are a guest in a dream, how can you feel comfortable when you are awake
etc…
It is inappropriate to write poems about ambitions.
It can be replaced by two other sentences -
I only wish that when I sing and drink, I can see the flowers in Chang'an as soon as the sun goes down!
Have the bills been cleared before being put on the shelves? OK, we are new. Let's all sleep today, there will be another class at noon tomorrow.
