Le Hollandais Volant#17868 - The Waiting Time Paradox, or, Why Is My Bus Always Late? | Pythonic Perambulations
In the case of a nominally 10-minute bus line, sometimes the span between arrivals will be longer than 10 minutes, and sometimes shorter, and if you arrive at a random time, you have more opportunities to encounter a longer interval than to encounter a shorter interval. And so it makes sense that the average span of time experienced by riders will be longer than the average span of time between buses, because the longer spans are over-sampled.
Amusant et intéressant comme paradoxe probabiliste.
Je ne connaissais pas celui-là.
