Teresa loves playing games. If the day is sunny, the probability that she plays tennis is 0.7. If it is not a sunny day, the probability that she plays tennis is 0.4. Also, the probability that Saturday will not be sunny is 0.15. Use a tree diagram to find the probabilities of these outcomes. a Teresa plays tennis on Saturday. b Teresa does not play tennis on Saturday.

A local "home TV repair service" company has two repairmen who make all of the home repairs. The company sends Repairman D on 70 percent of all jobs, because the likelihood of a "second follow-up call" within a week is only 0.08 compared to 0.20 for Repairman K. If you had a recent repair job that is going to require a second follow-up call, what is the probability that Repairman K did your...

A fair die is tossed repeatedly. The maximum of the first n outcomes is denoted by X n . Is {X n : n = 1, 2,...} a Markov chain? Why or why not? If it is a Markov chain, calculate its transition probability matrix, specify the classes, and determine which classes are recurrent and which are transient.

Consider a hospital emergent room that opens 24 hours a day. Suppose that the arrivals of patients are well modeled by a Poisson Process with rate per hour. a) A nurse starts her shift from 8am, what is the expected time to see her first patient in the day? If she starts a bit late, say 8:10am, answer the same question. (Please specify your assumptions.) b) If she already seen 12 patients by 10am,...

A petrol station owner is considering the effect on his business (Superpet) of a new petrol station (Global) which has opened just down the road. Currently (of the total market shared between Superpet and Global) Superpet has 80% of the market and Global has 20%. Analysis over the last week has indicated the following probabilities for customers switching the station they stop at each week: To...
