= In this exercise we will use a simplified mathematical model to analyze failures in a
distributed system. Explain your answers. Suppose each computer in has a probability of p of failing
at any time.
a) If n computers are interconnected and the availability of each computer is needed to maintain a
service provided using distributed computing involving these computers, what is the probability
that the service will not be available at any time, assuming that no other components in the
distributed system will fail?
b) Use p = 0.2 and n = 3 to compute the probability. How does it compare with the failure
probability if the same computing is performed using monolithic computing, that is, on one
computer only?
= t6
