Question 2: [CLO2.1, S1/S0.2, 0.5 Mark) Network reliability improves when redundant links are used. The reliability of the network in Question 1 can be improved by building two subnetworks in parallel as shown in the figure below. Thus, if one subnetwork fails, the other one will still connect. 5, 59 $10 -.. 39 510 a) Using the data in Question 1, determine the reliability of the network. b) If the reliability of this new network is required to be 0.999, what must be the failure probability of each link
