标题[问题] Poisson一问
时间Wed May 9 00:19:40 2012
谢谢大大们热情的帮忙，虽然本人自己一时糊涂搞错方向，还是很谢谢版友们的帮助
现在本人有一题Poisson想请教各位，希望能给一下思考的方向:
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?
这题很明显是用Poisson equation。但由於题目里面又提到"new supply will arrive
in eight weeks"请问考虑此因素要如何计算呢?谢谢大家了>///<
