SUMMARY
The classical Poissonian process describes the probability of an event occurring in a time interval dt as ωdt. The probability that the event has not decayed by time t is given by P(t) = exp(-ωt), derived from a differential equation. When ω is time-dependent, the probability function modifies to P(t) = exp(-∫₀ᵗ ω(u) du), requiring the solution of the differential equation P'(t) = -ω(t)P(t). This adjustment highlights the impact of varying rates on decay probabilities.
