SSI chips, essential to the running of a computer system, fail in accordance with a Poisson distribution with the rate of one chip in 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? 在網路上也看到這題但好像沒有正確的答案不知道小弟這樣解對不對將兩個chip當作獨立事件討論 -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 42.72.147.18 (臺灣) ※ 文章網址: https://www.ptt.cc/bbs/Grad-ProbAsk/M.1575395717.A.DC9.html ※ 編輯: edward0887 (42.72.147.18 臺灣), 12/04/2019 01:55:50 https://i.imgur.com/fYSzeqn.jpg
