The more Ma Wu thought about it, the more he felt that something was wrong, turned on the computer, checked it in the database, and was immediately stunned. The pen "fun" pavilion www.biquge.info only buy one note each time, almost every week to buy, but the three first prizes in Hebei Lao Zhangzhong, all in the prize pool accumulated more funds, or the first prize in the current period is less, so his first prize at the top of the other time four or five notes of the amount. In a year, winning three first prizes with more than 40 numbers is outrageous in itself, and every time you can catch up with the high prize money and few winners, can this old Zhang pinch will be counted?

But after thinking about it again, Ma Wu felt even more frustrated. If Lao Zhang knew the number in advance, why didn't he win the jackpot of five million? After all, there is only one number missing, and the prize is too much different. With the probability of winning the first prize, it is not easy to get a jackpot? Even if he does not win the jackpot, every time he buys a lottery ticket, he buys a few more bets, and spends a few hundred yuan a year, and the prize money can be multiplied several times? Such a simple way to get rich, Ma Wu did not believe that Lao Zhang did not see it.

He told his daughter-in-law about his confusion, and neither of them figured out the doorway inside. Ma five daughter-in-law told Ma five another thing,A few days ago,Director Hou of the lottery center came to inspect the lottery point,That day Ma Wu went to the store to buy goods were not there,Ma Wu daughter-in-law stuffed two cigarettes for Director Hou,Before leaving, Director Hou half-jokingly said, "Your lottery point is famous in the lottery center,The amount of winning a year is about to catch up with the sales amount,The first in the country." Thinking of Director Hou's words, Ma Wu's daughter-in-law felt even more unsteady, "Ma Wu, we have the first prize here, and we must let the lottery center focus on it, don't do anything, right?"

Ma Wu glared at him and said, "What can happen?" No one won the lottery before, and some people said that it was from the widow of Naliu before liberation, saying that the feng shui of our house was not good. Now there are more people who have won the lottery, and there are more red-eyed children, we don't steal or rob, and there is no relationship with that Hebei Lao Zhang, it's okay, take advantage of this good time, and let's come here to buy lottery tickets in the surrounding alleys. ”

Ma Wu said that, but Ma Wu's daughter-in-law mentioned the matter, so that Ma Wu realized that Hebei Lao Zhang should not be unable to win the jackpot, nor can he afford to buy ten notes and eight notes at a time, he must be afraid of being noticed by others, the second prize is often only one thousand eight hundred, too little, so he is eyeing the first prize. It seems that this Hebei Lao Zhang is really tired.

Ma Wu called up the lottery tickets that Lao Zhang bought this year to analyze, and let him really find some truths. That Lao Zhang should not know the specific winning number of each period, he will buy a set of numbers first, and has insisted on buying each issue, as little as seven or eight periods, more than ten or twenty periods, he will win a first prize, after winning the lottery, he will change a set of numbers, and keep buying. In other words, Lao Zhang knows which set of numbers will be won, but he doesn't know which one is in which issue. This ruled out any collusion between him and the lottery center. But how did he know that the set of numbers would win? Ma Wu was still puzzled.

Speaking of which, I have been deeply attracted by the story of Ma Wu, and I can't help but interject: "Ma Wu, lottery, gambling or something, I have never touched, nor studied, but I know that normal gambling is a matter of probability, and the probability of winning the banker is always greater than that of the player, so we will see good luck in the casino, win a lot in one night, but do not see more bad luck, lose all the money, so, the dealer as a whole is a pull, winning is actually the probability difference." Of course, if the dealer wants to win more, it is also to move some hands and feet in probability, not like the folk use a thousand ways. Do you think this is the same for playing the lottery?"

Ma Wu looked up at me in surprise and showed a rare smile: "Old Chang, don't you call this a study?

I poured wine into Ma Wu's glass, and continued: "It's a pity that gamblers are staring at those who win, and always feel that good luck will be spread on them next time, and they won't stop. But then again, the banker can ensure that he only wins and does not lose by manipulating the probability, but the player cannot be manipulated, and the lottery should also be the same. So the old Zhang you are talking about can know the exact winning number, which is absolutely impossible. ”

Ma Wu nodded, drank the wine in the cup in one gulp, and his eyes returned to their original gloom. continued.

"Who's to say it isn't. In the past, there was a kid in Nanchanggen Hutong, a top student in the computer department of Tsinghua University, who was obsessed with playing the lottery. Later, he said that he could simulate the winning number through a computer, and he also invented a software, and the principle should be the probability science that you often said, but I have never seen him win the jackpot. ”

I have a little impression of what Ma Wu said, and it has been reported in the newspapers. However, with computer-aided calculation, we can only use the probability model to reduce the possibility of a part of the combination with a low probability through the collection and analysis of the previous winning numbers, but the remaining number combinations are still huge, unless you spend a lot of money to buy all the combinations, you still can't ensure that you will win the lottery. But most of the time, this investment will exceed the possible winnings, which naturally has no practical meaning.

But I have the impression that although the Tsinghua lottery fan has never won the jackpot with software, he still sold a lot of software and went out to make a fortune. Sometimes you can't guess what a bettor thinks, and the worship of high-tech is no different from the worship of ghosts and gods.

"Ma Wu, I remember you just said that Hebei Lao Zhang used to be a middle school teacher, he wouldn't teach mathematics, right? "The afternoon sun in the small courtyard was a little dazzling, I moved the small table under the grape trellis, thinking to myself, this Ma Wu now likes to talk in circles, I don't believe that he is to talk about this strange thing, and specially bought two bottles of good wine to come to me.

Ma Wu took a sip of the wine in the glass, and it seemed that at this time, he really began to taste the aroma of the wine in the cup. "Chang, people, there are two levels that you can't pass, one is nosy, easy to inquire, and the other is a greedy word. ”

Since Ma Wu discovered Lao Zhang's secret, his curiosity has become heavier and heavier, and as soon as he came to the lottery spot, he wondered how Lao Zhang knew the winning number. When Lao Zhang came to buy lottery tickets, he deliberately went up to set up a few more words, hoping to find some clues from the chat. But the old mouth is very strict, as long as it involves the lottery, number selection or something, they are silent, left to talk about him. This made Ma Wu very disappointed.

But after a long time, Ma Wusheng dragged Lao Zhang to drink twice, and did not ask the mystery of winning the lottery, but learned some of Lao Zhang's life experience.

Hebei Lao Zhang is a native of Baoding, but he was born in the countryside, and the only way to get out of the countryside that year was to study and go to university. Lao Zhang is gifted in reading, one is excellent memory, and he is a little exaggerated when he sees it, but he really tried to memorize it backwards, and the accuracy rate of memorizing it backwards is more than ninety percent. The other is very sensitive to numbers, and he has a perfect score in his mathematics class and has insisted on it until his second year of high school, and he is naturally the top science student in the college entrance examination that year.

But Lao Zhang is sensible early, he knows himself very clearly, and his goal is very clear when he is admitted to university, and his character who loves more seriously can't go to a career in office, nor can he go to a state-owned enterprise, and he is not very good at dealing with people, and colleges and universities and research institutions are not suitable. He entered the normal school with the top result that year, which was also quite a sensational thing.

After graduating from university, he was assigned to a key middle school in Shijiazhuang as a mathematics teacher, and this teaching was more than ten years. During this period, he married a wife and had children, and the school allocated a spacious building, and Lao Zhang was responsible for teaching classes, and he was good for his children, and he was very good at inspiring children's curiosity about mathematics. In the early nineties, he was rated as an excellent teacher, and in ninety-four years, he was promoted to the head of teaching and research. If you go all the way in this life, you should be respected and have no worries about food and clothing. But perhaps only Lao Zhang himself knows the kind of unwilling ordinary impulse lurking in his heart.

In the summer vacation of the year when he was the head of the teaching and research department, he didn't make some extra money by taking a cram school or something outside like in previous years. Instead, I spent a leisurely holiday, visiting parks and vegetable markets during the day, and after taking a nap in the afternoon, I went fishing by the river on the outskirts of the city. When he was strolling around the park, he found a lot of people of the age grouping around to play mahjong and poker. Winning or losing is not big, and it is a game of ten dollars and eight dollars in the morning.

Lao Zhang had an ability when he was in college. Because he has a good memory, he remembers very clearly who has played what cards, and a few cards are played, and he can basically judge the opponent's cards out of eight or nine without leaving ten. Later, he found that as long as the end of a game, when shuffling the cards, the cards shuffled not so finely, so often, he can probably remember the order of the cards, what cards others get, he can naturally know everything. has this ability, the natural winning rate is super high, plus Lao Zhang never accepts it when he sees it, and when he wins, it will be endless, and he will look at him at night, making others bored, and no one in the dormitory will want to play with him later.

But the people in the park are not playing with the double buckles, tractors and the like that are often played in college, but with zakin flowers. Lao Zhang watched on the side for a few days, the rules of the game are not complicated, and the time of each game is short, the stakes in the pond are high, especially the players often have to calculate whether the call is not in the intention to take the loose cards to speculate, fighting wits and courage, very exciting, this game attracted Lao Zhang.

(If a good speaker is a skillful person, because of the power of man, because of his own strength, because of his coming and coming, because of his past, there is no image, and life and growth, and the sound of speaking, and prosperity and decline, and the return.) Although there is a lot of force, although the material is strong, it is necessary to control its life. Blowing with the wind, the sound does not add to the disease, and the sky is high and looking, and the eyes are not clear. That's why it's easy. --"Lü's Spring and Autumn")
