Webb6 Stopping times and the first passage Definition 6.1. Let ( Ft,t ≥0) be a filtration of σ-algebras. Stopping time is a random variable τ with values in [0 ,∞] and such that {τ ≤t}∈F t for t ≥0. We can think of stopping time τ as a strategy … WebbOut of these 27 values, 10 were successes, in proportion 10 / 27 (which is consistent with p = 1 / 3 = 9 / 27 but varies from it due to chance). Notice that the stopping rule changes the sequence not one whit: it merely marks the boundaries between successive experiments.
