1, select numbers by exclusion method.
Rank the number occurrence rate of 0 1~33, and exclude the number with low occurrence rate. The basis of excluding numbers is to judge according to the proportion of old and new numbers. If the occurrence rate of old numbers (lottery numbers within five periods) is relatively large, then numbers exceeding five periods can be selectively excluded.
2. Use hyphens to select numbers.
The lottery first looks at the trend chart of 30 consecutive numbers, and then observes which numbers are more relevant. For example, if you think 18 has a good chance of winning a number, then consider the serial numbers of 17, 18 or 16, 18. The probability of hyphenation is about 80%. Because it is very common, hyphenation is the first choice when choosing numbers.
3. Use duplicate codes to select numbers.
Duplicate code refers to the number that pops up continuously. Among them, the probability of double code and three code is higher. Don't ignore the duplicate code in the selection of two-color ball. If the lottery masters the occurrence law and proportion of repeated numbers, then the distance from winning the prize is close!
4. Use hot and cold codes to select numbers.
Hot codes are numbers with high frequency, while cold codes are numbers with low frequency. Because lottery numbers can't be all hot codes or all cold codes, it's best to combine hot codes and cold codes organically in the process of selecting numbers. Consider three hot codes with three cold codes, or choose a combination of four hot codes with two cold codes.
5. Choose numbers by mathematical calculation.
According to the principle of probability, the frequency of red balls in the past 33 periods of two-color ball is calculated, and the probability of these numbers appearing in each period is obtained by dividing the number of times of occurrence by the number of periods. For example, in the lottery of 10, 09 appeared twice. Divide 2 by 10 to get 0.2 times 100%, that is, the probability of 09 appearing is 20%, and the choice is decided according to its hot and cold degree.
