If there are 120 objects in a population and the investigator wants to use simple random sampling to choose objects in to a sample from this population, what is the probability of a object to be selected in to a sample?

any types of probability samples are available for sampling from a population. The most basic sampling method is the simple random sampling. The simple random sample from a population is a sample that is selected so that each possible sample combination of the specified size has equal probability of being chosen. In practice, a simple random sample is usually called random sample.

Select the first sample element by giving each of the N population elements an equal probability (1/N) of being chosen.
Therefore the answer is 1/120
