A train company is hiring mining companies to dig a tunnel A train company wishes to dig a new high-speed train tube from London to New York and is taking proposals from various companies. To save time the chosen company will need to begin digging 2 tunnels simultaneously from the two exits and attempt to line it up perfectly into one finished tunnel. A representative from a German corporation comes to the train company to presents their proposal, "It will cost you 2 billion dollars and will take 7 years to complete and there is a 5% chance that the two tunnels will be off by .2 meters." The executives at the train company appreciate the offer but keep looking. A representative from a Chinese corporation comes to the train company to presents their proposal, "It will cost you 1.5 billion dollars and will take 5 years to complete and there is a 3% chance that the two tunnels will be off by .4 meters." The executives at the train company appreciate the offer but keep looking. Finally a representative from a Russian corporation comes to the train company to presents their proposal, "It will cost you 100,000 dollars and will take 1 year to complete and worst case scenario you'll have two tunnels." (i translated this joke from russian so hopefully the humor carried through)
