In Exercises 51 and 52, consider another two-dimensional random walk governed by the following conditions.
● Start out from a given street corner, and travel one block north. At each intersection:
● Turn left with probability
● Go straight with probability
● Turn right with probability
(Never turn around.)
A Random Walk Using a Random Number Table Use Table 20 to simulate this random walk, For every 1 encountered in the table, turn left and proceed for another block. For every 2 or 3, go straight and proceed for another block. For every 4, 5, or 6, turn right and proceed for another block. Disregard all other digits-that is, 0s, 7s, 8s, and 9s. (Do you see how this scheme satisfies the probabilities given above?) This time, begin at the upper right corner of the table, running down the column 2, 6, 0, and so on, to the bottom. When this column of digits is used up. stop the “walk.” Describe, in terms of distance and direction, where you have ended up relative to your starting point.

- Smokers and Non smokers In a population of 10,000, there are 5000 non-smokers, 2500 smokers of one pack or less per day. During any month, there is a 5 probability that a nonsmoker will begin smoking a pack or less per day, and a 2 probability that a nonsmoker will begin smoking more than a pack per day. For smokers who smoke a pack or less per day, there is a 10 probability of quitting and a 10 probability of increasing to more than a pack per day. For smokers who smoke more than a pack per day, there is a 5 probability of quitting and a 10 probability of dropping to a pack or less per day. How many people will be in each group a in 1 month, b in 2 months, and c in 1 year?arrow_forwardConsumer Preference In a population of 100,000 consumers, there are 20,000 users of Brand A, 30,000 users of Brand B, and 50,000 who use neither brand. During any month, a Brand A user has a 20 probability of switching to Brand B and a 5 of not using either brand. A Brand B user has a 15 probability of switching to Brand A and a 10 probability of not using either brand. A nonuser has a 10 probability of purchasing Brand A and a 15 probability of purchasing Brand B. How many people will be in each group a in 1 month, b in 2 months, and c in 18 months?arrow_forward
