Pr. 3 Production. In a production process, let N mean "no trouble" and T"trouble." Let the transition probabilities from one day to the next be 0.8 for N ->>> N, hence 0.2 for N ->>> T, and 0.5 for T → N, hence 0.5 for T→ T. If today there is no trouble, what is the probability of N two days after today? Three days after today?

3. [From Meyer 1970] The following (somewhat simple-minded) weather forecasting is used by an amateur forecaster. Each day is classified as "wet" or "dry" and the probability that any given day is the same as the preceding one is assumed to be a constant p (0 < p < 1). Based on past records, it is supposed that January 1 has a probability of B of being "dry." Letting Br=probability (that the nth day of the year is "dry"), obtain an expression for Bn in terms of B and p. Also evaluate lim Bn and interpret your results.
