A computing system is composed of two servers that are mirrors of each other (for redundancy, so if one fails, it can be restored from the other). Assume that each server has an expected MTBF of 500 hours and its continuous uptimes (the average of which is MTBF) follow an Exponential Distribution. Furthermore, assume that when a server fails, it takes exactly 10 hours to restore the data from the mirror. (a) Write a program that generates synthetic data showing the failure and restoration times for each server over 20 years. You can assume it is always exact 24 hours per day and exact 365 days per year.

Question
A computing system is composed of two servers that are mirrors of each other (for
redundancy, so if one fails, it can be restored from the other). Assume that each server
has an expected MTBF of 500 hours and its continuous uptimes (the average of which
is MTBF) follow an Exponential Distribution. Furthermore, assume that when a server
fails, it takes exactly 10 hours to restore the data from the mirror.
(a) Write a
times for each server over 20 years. You can assume it is always exact 24 hours per day
and exact 365 days per year.
