Where the article explains it
The first rises with k ; the second falls.
The passage around this formula
Code-generation research often reports k : the probability that at least one of k sampled solutions passes. If independent attempts each succeed with probability q , then . This is valuable for search: more attempts increase the chance of finding one acceptable candidate. Production consistency asks a different question. If k required deployments must all succeed, the same independence simplification gives
