Simple random sampling gives every unit an equal chance. With $N$ units, one is chosen at the first draw, so each unit's probability is $\frac{1}{N}$ .

Reasoning. In simple random sampling (without replacement) from a population of $N$ units, all units are equally likely to be selected. At the first draw there are $N$ equally likely units and exactly one is pick …
