謝謝大大們熱情的幫忙,雖然本人自己一時糊塗搞錯方向,還是很謝謝版友們的幫助 現在本人有一題Poisson想請教各位,希望能給一下思考的方向: SSI chips, essential to the running of a computer system, fail in accordance with a Poisson distribution with the rate of one chip n about five weeks. If there are two spare chips on hand, and if a new supply will arrive in eight weeks, what is the probability that during the next eight weeks the system will be down for a week or more, owing to a lack of chips? 這題很明顯是用Poisson equation。但由於題目裡面又提到"new supply will arrive in eight weeks"請問考慮此因素要如何計算呢?謝謝大家了>///< -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.115.203.211
