Question

which best describes a random sample? a sample in which the elements are chosen by chance a sample in which the chosen elements are predetermined a sample in which each element of the population is chosen a sample in which the chosen elements are removed from the population once they are chosen

Explanation:

A random sample is one where elements are selected by chance, giving each element in the population an equal probability of being chosen. Predetermined elements are not random. Choosing every element of the population is a census, not a sample. Removing chosen elements is related to sampling without replacement, but not the core definition of random sampling.

Answer:

a sample in which the elements are chosen by chance
