GB 10111--88
2.1 Sampling: The process of randomly selecting or forming a sample. 1.2 Simple random sampling: Selecting n individuals from a population of N individuals so that all possible combinations of n individuals have equal probability of being selected.
According to the definition of simple random sampling, the probability of each individual (or product of each individual) in the population being selected is equal. 2.3 Symbols:
Total number of people:
The number of people R obtained by the method of broadcasting the number of shares
The random number R determined by the method of reading the specified part.
Integer part:
When the integer
is large, the integer part of

Through the river line, with, facing the low end of the load, the standard heart of the stock now the number of small self-causing number, out of the mountain now the number of the heart: the collection is also a number than the heart appears in the table. Choose the regulations, the general number is often when, small \. Will do it!

Batch draw year single core or outstanding product technology natural number from "【" and start serial number, then use the installed number to match the number. Deng Xie selects single or unit production activity without "all numbers", for example, the big and small opening license, you can also get the random number first, then the number, according to the number of sensitive draw.
