This method is simple, but there may be some problems, such as the randomness of random number generator is not high enough, the design of rules is unreasonable and so on.
2, box extraction
In some traditional lottery activities, the number of participants will be put into a lottery box, and then the staff will draw the winning numbers. This method is intuitive and fair, but there may be some problems of human operation, such as someone deliberately choosing a certain number.
3. Shake it with a lottery machine
In some activities of buying a house by lottery, the winning number is obtained by lottery machine.
