Quetion 3. In the traneportation network below, let an link i = 1 , 2 , , 5 0 , 12 , 13 , 4 , and 16 minutes, From historical records, we have good estimations of the link traver . matrix is also known: respectively for ench link i = 1 , 2 , , 5 . The covariance tman a) Explain how to use the central limit theorem to answer questions b), c) and d) below. b) What is the fastest route from A to B in terms of the expected travel time? c) What is the probability that route A D B is faster than A C B? d) What is the probability that route AD B is faster than A C D B?
