Occurring a bug in software follows poisson distribution(mean
= 100). Each bug becomes an error independently after certain time
which follows exponential distribution(mean = 10).
When an error appears in system, it will be eliminated
immediately.
(1) After 100 hours, find probability that number of
eliminated errors is 5
(2) Find the expected number of bugs still remain in
software.
(Solving process could be related to binomial
distribution)
Thanks in advance
