Question

The weather on any given day in a particular city can be sunny, cloudy, or rainy. It has been observed to be predictable largely on the basis of the weather on the previous day. Specfically:

  • if it is sunny on one day, it will be sunny the next day 3/5 of the time, and be cloudy the next day 1/5 of the time
  • if it is cloudy on one day, it will be sunny the next day 1/5 of the time, and be cloudy the next day 3/5 of the time
  • if it is rainy on one day, it will be sunny the next day 3/5 of the time, and be cloudy the next day 2/5 of the time

Using 'sunny', 'cloudy', and 'rainy' (in that order) as the states in a system, set up the transition matrix for a Markov chain to describe this system.

Find the proportion of days that have each type of weather in the long run.

(here's a sample of what the answer would look like)

The correct answer is:
P =
25
