The passage around this formula
That gap is large enough to be worth writing down explicitly. If a task’s outcome were an independent Bernoulli draw with a fixed success probability p equal to the reported average, the probability that all k independent attempts at the same task succeed would be . At p = 0.60 and k = 8 , that model predicts roughly 1.7%. The reported figure — under 25% — sits well above that naive prediction, and the direction of the gap is informative on its own: it is only possible if outcomes are not independent draws from one fixed probability, but rather reflect a task population that splits into instances the agent reliably solves and instances it reliably does not, with the…

An exponent tells how a base is used in multiplication. In x³, x is the base and 3 is the exponent: x³ = x × x × x.
