Question
**Q4 **: Suppose a worker is assigned to check the entire system failure and is
responsible for handling it (again, by just resetting both routers). There is a
one hour lunch break from 1 pm - 2 pm. what is the probability that the entire
system will fail at least once within this lunch break time? Also, what is the
probability that there will be no failure within the lunch break? Assume that the
system failures also follow a Poisson Process
a) Describe what are the probabilities in question in ter ms of Pk(t)
(probability of k events occurring during time t). You need to think carefully of
various properties of the Poisson process.
Answer Part a Here
b\. calculate those probabilities using R and the total system failure sample
(you will need to use the formula, no special R techniques here). e\x is exp(x)
in R.
