physical connection between three routers , the links have 0.2 probability of being cut during a transmission . each link is independent of another
1) what is the probability that there is at least one working path from a to c?
2 if a new link is added to this network and the link has the same probability of being cut(0.2) compute(1) again if the link is added:
a ) between a and b
b )between b and c
c ) between a and c
