Unformatted text preview: more detailed life table 3. (extra) Suppose you are standing at an intersection in Manhattan, and you want to go home. But temporarily, you have forgotten where you are, and so you try to perform a random walk: With equal probability, you start walking north, west, south, or east to the next intersection. However, you are not that much lost that you forget from where you came, so if you decide to go north in one step, in the next step you will only go north, east or west, but not back south. (a) Simulate a few random walks of length 10. Measure the distance from the starting point. (b) How many diFerent random walks of length n are there? (c) Can you nd an estimate for the average distance from the starting point with a random walk of length n ? (d) Do you think you will ever get home? Please bring a computer to class next Wednesday!!!...
