Equation 12 · Part 4 · Measuring AI Agent Reliability: What the Evidence Actually Supports
Symbol n
What this part means
the two formulas share the same.
Its job in the formula
n appears inside an expected value, so its contribution is averaged under the distribution or condition shown by that operator.

Where the article explains it
The two formulas share the same n , c , and k and the same combinatorial machinery, and that similarity is precisely the point: they are estimating two different probabilities from the same data, one about the best of k attempts and one about the consistency of all k of them.
The passage around this formula
…under domain policies, proposed the complementary statistic: the probability that every one of k independent trials on the same task succeeds, rather than at least one of them [ 3 ] . The two formulas share the same n , c , and k and the same combinatorial machinery, and that similarity is precisely the point: they are estimating two different probabilities from the same data, one about the best of k attempts and one about the consistency of all k of them. A system can score well on the first and badly on the…

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.
