I Am Not A Mage Lord

　　 Early the next morning, Lynch, who had gambled all night with the dragon inheritance in his mind, was glamorous with dark circles.

　　 The entire gambling market made the Dragon Legacy spit out a lot of basic dragon language runes with two lines of changes and predictions.

　　 But there are too many, Lynch can't make the delivery for the time being, and can only save it first, at least the bricks on his path to the mage are thicker.

　　 When Lin Qi just walked out of the secret alleyway, he happened to meet Wang Ruoling, who was carrying a basin and toothpaste towel, and was going to wash up. There was also a delicate girl beside her.

　　 "Why are you here?" Wang Ruoling was surprised.

　　Girl Enya also looked at this handsome man.

　　 This habit of rubbing on the girls floor is unhealthy.

　　 Lynch hurriedly broke the topic, "I just thought about some gambling betting theories, and I didn't pay attention to getting around here."

　　 Sure enough, "gambling" hit Wang Ruoling's death orifice and swept all her attention away, "Then you tell me?"

　　 Lynch immediately confided the betting ratio formula and quotations, and Wang Ruoling, who is an "anti-gambling faction", should indeed have some theoretical support.

　　 In fact, the "Kelly formula" is a betting strategy that is applied in independent repeated betting where the expected net income is positive to maximize the long-term growth rate of the principal.

　　 Facing the strategies in life also works.

　　Such as two expedition teams, the probability of a successful return from the journey is 40% and 60%. Once successful, the resources they will explore on their return journey will depend on the resources invested at the time of departure, with additional feedback of 130% and 100% respectively.

　　 How to arrange the resource input ratio of the two teams in this case?

　　 So in the blackjack game last night, Lynch was able to calculate the "winning rate" based on the cards, and then combined with the "odds" given by the opponent to naturally calculate the betting ratio.

　　Wang Ruoling listened, and couldn't help muttering to himself and repeating the formula.

　　 "Bet ratio = (winning rate * net odds-losing rate) / odds."

　　 "Oh, once the "expectation" of winning rate * net odds is equal to or less than the losing rate, the result will be 0 or negative. I think it is not worth investing, but gamblers don't know the truth."

　　 Lynch smiled. They were all human beings, and they understood at once.

　　 For example, toss a coin to guess the positive and negative game, each time 1 yuan is invested, 1 yuan will be confiscated for the wrong guess, and 1 yuan will be paid for the correct guess.

　　 This looks like an absolutely fair game, winning rate * odds-losing rate = 0.5 * 1-0.5 = 0.

　　 That's right, an absolutely fair game, with zero revenue expectations!

　　 is not worth playing this game at all!

　　 Enya, a young girl apprentice with a keen business sense, commented, “Actually, the casino is fair and the winning rate is 50%. But because of the banker’s pumping, the gamblers’ expectations are completely negative.”

　　 "It's ridiculous that casinos with negative returns have attracted gamblers."

　　 Lin Qi nodded silently, agreeing.

　　 The 10 hands that were constantly refreshed last night, he was only betting on the positive returns, and just discarded the others.

　　 forced him to give up until the end that the dragon inheritance brushed out all "negative profit" bets.

　　 Wang Ruoling reacted and introduced Lynch and Enya to each other, and Lin Qi realized that this was the buyer of his points.

　　 "Then, classmate Lynch, what do you think the casino relies on for making money?" Enya the girl suddenly asked.

　　 Lynch was taken aback. Last night he seemed to use the "Kelly formula" to earn free knowledge passed down by the dragon.

　　 But in fact, he relied on another formula.

　　 "Didn't you just say that because the casino takes a 5% off, the fair game turns into a negative return, so the casino wins the gambler's money and relies on the final turnover."

　　 The girl Enya's expression was shocked, the answer was exactly the same as her father told her!

　　 somewhat counter-intuitive, but extremely profound.

　　 "Your keenness is really good, no wonder you are our best student in this class." Enya praised.

　　 Lynch was already far away at this time, and his voice came through far away.

　　 "No, these are what math told me."

　　 "According to Bernoulli's law of large numbers, under the condition that the experiment is unchanged, the experiment is repeated many times, and the frequency of random events is similar to its probability, and there is a certain certainty in accident."

　　 Saying that Lynch's figure has disappeared at the intersection.

　　 So the final money made by the dealer depends on the gambler’s total investment and multiplied by 5% of the rake.

　　 is like the "minimum bet amount" means to increase the total bet amount.

　　 Gamblers never know that the game they think of is simply comparing mathematicians like Dirichlet, Bernoulli, Gauss, Nash, and Kelly to mathematics!

　　 The casino doesn't care who wins at all, anyway, it will eventually comply with the law of large numbers and send it back to them through pumping.

　　 I'm not afraid of you winning, I'm afraid you won't bet!

　　Enya couldn't help biting her lip, looking at her companion next to her, "Ruoling, your friend, you are a little cool."

　　 "And do you know? The theory he just told me is the key foundation of the prophecy spell. I have to talk to my aunt and tell her that our current Lynch is probably very talented for prophecy."

　　 She took out the mobile phone that her aunt quietly gave her, and silently entered a paragraph.

　　Wang Ruoling couldn't help but raised her eyebrows slightly, she always felt a little familiar with these words.

　　-----------

　　 The first class "Summon of the Guardian Spirit" on the second day of school is regarded as a great battle course since the beginning of school.

　　 In addition to the uniform start of classes for all one-year apprentices, the college has sent a large number of teachers for this course, and the atmosphere is solemn.

　　 When Lynch rushed to the classroom, the five wizards who served as the "spirit-opening ceremony" were already there. Looking at the style of the robe, there were no shortage of middle-high ring wizards.

　　 They looked indifferent, and at the same time the invisible servants couldn't help carrying ritual objects towards the auditorium classroom.

　　 Facing this may be the only chance to come into contact, most of the apprentices below are very busy, ready to wait for a blockbuster and impress these powerful wizards.

　　 Suddenly a female mage lowered her head slightly, glanced at the phone in her cuff, her pupils were slightly open, and then she glanced at the audience with kindness, and then she was silent.

　　 "Why do you look depressed?"

　　 Because of its large scale, the entire auditorium was crowded with no fewer than hundreds of people. Lynch managed to squeeze through the crowd to find his roommates.

"Brother Lin, I haven't congratulated you on the behavior of turning the audience on the show last night. You slapped Zhao Qi in the face severely. It is said that a group of them shouted while everyone was asleep in the middle of the night. Yes." Chen Shikun hurriedly reported to Lin Qihui.

　　 Lynch had to hold back his smile, in fact he heard it last night too, presumably no one will provoke him again, right?

　　 In the face of this kind of thing, only one punch is required, so you can save a hundred punches!

　　 "At the end of the day, I looked depressed. It was an apprentice who committed suicide last night. We felt it was a pity." Chen Shikun sighed.

Liu Kai on the side took the stubborn words, "Yes, especially in this'Guardian Spirit' course. It is said that every apprentice of the mage who successfully opens spirits will receive great attention from the academy. Basically, those who successfully open spirits are destined to be sent. Central area."

　　 "So everyone is gearing up, but I am afraid that I am not talented enough, and I am under a lot of pressure, and I am afraid of becoming the next suicide."

　　 Even Liu Kai, who was the most cheerful in the past, was like this. Lynch also realized that this class was invisibly another test, weighing heavily on everyone's hearts.

　　The tall and thin Mo Yifei added, "Especially our dormitory has successfully summoned demons. If we haven't had a spirit opening ceremony this time, I really can't afford to lose that face."

　　 Chen Shikun suddenly refused to accept, "What are you talking about, everyone is not sure, Lin must have passed it."

　　 Lynch was hehe in his heart.

　　 Feelings Chen Shikun usually had such confidence in him, it seems that this little brother confiscated it in vain.

Chen Shikun said, "Brother Lin, the academy’s largest underground gambling market, Absolute Libra, has opened a lot~www.wuxiaspot.com~ Many people in our dormitory have pressured their dormitory to awaken first, so everyone is holding their breath. Woolen cloth."

　　 "Oil lamp share?" Lynch was surprised.

　　 All of them nodded in embarrassment, "I heard that there are people who have reduced their share for a month, and some very important dragon sensors. Anyway, they accept everything. They have been operating in the academy for many years."

　　 Lynch pouted, isn't that a gift of money.

　　 "Is there anything about me?"

Chen Shikun's eyes widened suddenly, "Brother Lin, how did you know? There are two that are quite popular, one is whether you can summon the guardian spirit first and lose five. The other is whether you can successfully summon the guardian spirit today. , And at least lose one."

　　 Lynch wondered, what is the odds for his smashing performance?

　　 So look down on people?

Guo Sifei on the side was afraid that Lin Qi would underestimate the enemy, and explained, "Student Lin Qi, don't be careless. Guardian spirits also look at ritual awakenings, like us who have no foundation, rely on their own souls. But those descendants of the mage family can It is said that I have prepared for this moment after birth, and I don’t know how many methods are used to strengthen the soul!"

　　 "Our struggling faction, temporarily succumb to this wave." Guo Sifei also admitted.

　　 "Brother Lin, if I suppress you, you can definitely do it. They just send me money." Chen Shikun said righteously.

　　 Lynch was a little embarrassed, and looked around to see if there were any strangers.

　　 "This? Can you win by yourself?"

　　 This time, he was really well-informed.

　　 Because of the guardian spirit, he really has it.

　　 After all, if the winning percentage in the Kelly formula is 100%, then the betting ratio is 100%.

　　This wave, I'm allin.
