perhaps, an example would help:
let's say, 30% of population of Whoville had blue eyes, and 70% brown eyes.
let's pick a few whos at random.
each one, coming from the same population, has 70% chance of having brown
eyes and 30% blue eyes, that's the distribution X. but the actual eyes of
the actual who are of actual certain color- either blue or brown, and that's
the sample observation x.
so who #1 (whose eye color is distributed as brown 70% etc). is observed to
have blue eyes- that's first observation;
who #2 (who also have a 70% chance to have brown eyes and 30% to have blue
eyes) is observed to have brown eyes -that's the second observation, etc.
helps?
