CEVAP:

The following procedure selects a simple random sample with size n without replacement from a finite population with size N.
1. Select the first sample element by giving each of the N population elements an equal probability
(1/N) of being chosen.
2. Select the second element by giving each of the remining N–1 population elements equal probability
(1/(N–1)) of being chosen.
3. Repeat this procedure until all n elements are chosen.
