Chapter 116

A disc-shaped object is lying upright in the mall, emitting soft and extravagant golden light.

The light flashed, and Wang Yan smelled the smell of getting rich.

Take a closer look, it's actually a turntable?

Hey, what a fresh prop!

[Euro African turntable (primary)]

[usage times: 1]

[price: 1 million]

[Note: some people always think they're European, but they're actually black. Don't talk and spend money to test!]

Oh, I'll go!

Broken props are provocative, huh?

Wang Yan was a little unconvinced. He rolled his arms and sleeves. He wanted to try it right away.

However, after reading the specific details... Wilted.

The turntable has 10 grids in total, which are equally divided, and each grid accounts for 10%.

There are four colors: white, green, blue and gold.

White is three spaces. There are no prizes in it, but four words are written. It is not a relatively polite "thank you for your patronage", but a bone piercing ridicule - non chieftain rolling thick!

Obviously, the turntable has a 30% probability of losing everything.

One more level, it's four squares of green.

The four prizes are different. Wang Yan first focuses on the price. The cheapest one costs 200000 in the mall, and the most expensive one costs 800000 in the mall.

In other words, there is a 40% probability of blood loss of 200000-800000.

There are only two blue prizes, with prices of 1.5 million and 2 million respectively.

The last one is the golden reward, the price is... 5 million!

Therefore, the result is obvious. Wang Yan knows from his math knowledge in primary school that 40% probability of small loss, 30% probability of no return, 20% probability of small profit and 10% probability of big profit.

"Hooligan!"

Brother Fugui is very angry and is extremely dissatisfied with the black heart system.

If the probability of winning or losing is 50% to 50%, it can at least be regarded as a fair bet. It's really wrong. It's no wonder who is unlucky to hit the wall for a while.

What the hell is this now?

70% probability of loss!

Silly beep just played with you!

After scolding, Wang Yan glanced at the cash in the panel, removed the 100000 yuan paid for Chen Xiang, and 1.62 million was available at any time, and then gritted his teeth.

"Payment!"

Remaining salary: 620000.

System experience: 7192500.

Items held: Son of destiny, extraordinary force card, double flavor food card, see sincerity after drinking card, Oufei turntable (primary)

what the fuck?!

Didn't you say no gambling?

Mr. Wang, why are you so inflated?!

Wang Yan hasn't really expanded.

The result of primary school mathematics is blood loss, so you are primary school students, hehe.

Brother is 79's intelligence, the best of the best!

And just finished the basics of statistics, that's really not for nothing.

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 and designed gambling projects are applying this concept.

For example, the Las Vegas roulette similar to the euro African Roulette has a total of 38 grids, corresponding to 38 numbers. You can bet on a single number for $1 and get $35.

The mathematical expectation is calculated and 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 number of samples is large enough (enough gamblers), it will make no loss.

Therefore, regular casinos do not have to pay thousands at all. They can make money every day by recruiting a wide range of customers.

After make complaints about the black heart of the system, Wang Yan instantly calculated the mathematical expectation of the European and African turntables.

（500 × 10%）+（200 × 10%）+（150 × 10%）-（80 × 10%）-（60 × 10%）-（40 × 10%）-（20 × 10%）-（100 × 30%) = 350000

Mathematical expectations are positive.

This means that as long as you play enough times, you can earn 350000 for each time on average.

Silly beep doesn't gamble!

Not only bet, but also bet until the end of time!

You come out of the mentally retarded system and refresh a turntable for my brother every week. Dare you?!

System: O ((⊙⊙) O

If the system has wisdom, it will curse its mother.

I give you so much money to go out every day. If you don't drive well, you'll learn those messy things!

Take the math knowledge pit system, what are you!

（╯‵□′）╯︵┴─┴

Fall!

……

However, the system has no intelligence, so the room is very quiet, only Wang Yan's excited breathing.

"Start the lottery!"

The turntable turns and turns, and the pointer sweeps all the way over white, blue, green and gold

Finally, it passes through another white area by a millimetre and finally stops in the green area.

Hemp egg!

Lost!

However, Wang Yan only complained, but he had no regrets.

It's impossible to earn every time you play probability, but as long as the system doesn't change the design and the mathematical expectation remains positive, Wang Yan dares to play with ya until the sea withers and the rocks crumble.

Shenhao who knows mathematics is so confident!

He took out the final reward. Wang Yan was happy when he saw it.

Huh?!

Seems to have nothing to lose?

The prize is a skill book.

[hard pen calligraphy (Master level regular script)]

[improve your hard pen writing level to master level, only one step away from the master]

[price: 400000]

[Note: only in regular script. Authentic, Xingli, Li, Cao, Zhuan and other calligraphy styles need to be learned by yourself]

Master regular script, is it useful?

Not much use.

In modern society, there are fewer and fewer places to write, not to mention Wang Yan's arrogance. There are absolutely few opportunities to write something.

But another question: is it worth it?

It's so worth it!

How can it not be worth paying 1 million for a master skill?

As a God, you can never be short of money.

Therefore, anything that can improve one's own quality is worth it as long as it can be exchanged with money.

Wang Yanmei used up the skill book. In a moment, a vast amount of knowledge poured out of her mind.

There was a pen and paper on the desk. Wang Yan sat down happily, meditated slightly, and wrote down four names.

Wang Dayuan, Wang Xiufang, Wang Yan, Liu Li.

Iron bone silver hook, upright and dignified.

Wang Yan was overjoyed. After thinking about it, he added a fifth name.

He Meng.

Slightly deformed, it is no longer a correct regular script, but it is more delicious than at the beginning.

Because, more of their own style.

79's intelligence and comprehension are so strong.

In fact, writing has always been Wang Yan's short board. Although it is not as low as the level of crooked primary school students, it is absolutely not good-looking. It can be called "structure without structure, line without line".

However, as a student with normal aesthetics, Wang Yan knows what kind of words are good-looking and likes reading them very much.

Wang Yan's secret love for he Meng is not only because she is beautiful. When she was a senior in the blackboard newspaper, her beautiful blackboard writing was amazing to the boys in the class.

Later, he Meng's academic performance gradually fell, and the eldest lady's temper became more and more prosperous, but that word was always a good thing in Wang Yan's memory.

Don't exaggerate.

When a girl is beautiful and has some elegant attributes, that kind of lethality is definitely penetrating damage.

Now Wang Yan and Wang Hao have no love for he Meng.

However, after suddenly getting the master hard pen calligraphy, I couldn't help thinking of her and the little feelings I once had.

In a month's time, my friend has soared in appearance, height and body shape. Even calligraphy has surpassed you. It's like a dream

Ha ha, what a cool dream!

Wang Yan got up, stuffed the first calligraphy work in his life into the shredder and stretched himself leisurely.

I don't know if I'm a guest in my dream. How can I be comfortable waking up!

Wait

It is inappropriate to chant ambition with poetry.

It can be replaced by two other sentences——

I wish I could see the flowers of Chang'an at the end of the day when singing to wine!
