Answer:
Random sample: every element of the population has a (nonzero) probability of being drawn.
Simple random sample (SRS): every element of the population has the same (nonzero) probability of being drawn. SRS is thus a special case of a random sample.
The inverse of the selection probability can be used to weight the sampled data. The weighting is easier with SRS (than with other types of random samples) because all cases have the same weight.
