The number written next to each link of the network shown below is the probability of the link failing during the lifetime of a virtual circuit from node A to node B. It is assumed that links fail independently of each other. Find the most reliable path from A to B. This problem is equivalent to finding the path with minimum cost, for which we can use Dijkstra's algorithm, as shown in the table below the graph. Show your work.

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

Please give me correct solution.
In the small world experiment, it was observed that anyone in the world could reach any other person in the world in about 5.2 intermediates (thus 6-degree of separation). This observation was made more than 50 years ago. The Internet should have shortened this average path distance. Suppose with the use of Internet and online social networks, every person in the world increases their number of friends by doubling it (2x). Please estimate the new degree of separation. Explain your estimation.
