Answer :

Final answer:

A random sample is a subset where every member has an equal chance, ensuring a fair representation of the entire population.


Explanation:

Random sample is a subset of a larger population where every member has an equal chance of being selected. This allows for generalizing results to the entire population.

Simple random sampling ensures each member has an equal chance of selection, avoiding bias in the sample.

In contrast, samples like selecting all girls or boys with specific characteristics do not represent a random sample.
