[理工] [機率] 92台大電子(甲)
A fisherman catches fish in a large lake with lots of fish at a Poisson
of λ fish per hour. If, on a given day, the fisherman spends randomly
anywhere between c and d hours in fishing (i.e. his fishing time is a random
variable of uniform distribution over [c,d]), find
(a) the expected value and
(b) the variance of the number of fish he catches. 【92 台大電子】

對這種隨機變數的隨機變數一直是苦惱 ...
想請教各位 若是遇到這種隨機變數又被其它隨機變數影響的題目
該如何去思考他的意思 謝謝
