想問一題混和分配問題
題目是 Suppose that number of minutes between successive arrivals of the
Taipei MRT train at a station is uniformly distributed on (0,1). passengers
arrive according to a poisson process with a rate λ. Suppose a train has
just left the station. Let X denote the number of people who get on the next
train. find E(X)
答案是說t~U(0,1) 則X|t~poi(λt) 之後略
最常算二項跟poi的混和問題
但這題X|t~poi(λt)我搞不懂怎麼來的
請問高手如何解?或該翻那些資料加強觀念?謝謝
