The passage around this formula
…them pass — has an undesirable property: it is a valid estimate but a high-variance one, since it throws away information every time you happen to generate more or fewer than k samples. Their fix was to over-sample: draw n total samples per task, observe how many of them, c , actually pass, and then compute the exact probability that a random draw of k items from those n would contain at least one success [ 2 ] . That combinatorial form is the unbiased estimator: it uses every one of the n observed outcomes rather…

A variable is a named place for a value. Its letter is a local label: x can mean position in one formula and a data point in another.
