"Let's say you have already waited for 5 minutes (t=5). The memorylessness property means that the probability of the bus arriving in the next minute remains the same as before, i.e., 0.09516...≈0.1. The fact that you have already waited for 5 minutes does not affect the future probability of the bus arriving in the next minute."
你唔知個rate係一回事
但數學上個rate確實存在，的士既分佈亦應該好接近poisson distribution
只要落場數一次，平均每小時有z架的士出現，就可以計到expected waiting time = x = 60/z minutes
重點係巴士同的士間距個distribution唔同
前面咪話咗 correlation not causation 我係問緊 not causation 係咪即係 independent event
