Milwaukee's General Hospital has an emergency room that is divided into six departments:

(1) The initial exam station, to treat minor problems or make diagnoses;

(2) An x-ray department;

(3) An operating room;

(4) A cast-fitting room;

(5) An observation room for recovery and general observation before final diagnoses or release;

(6) An out-processing department where clerks check patients out and arrange for payment or insurance forms.

The probabilities that a patient will go from one department to another are presented in the table below:
(a) Simulate the trail followed by 10 emergency room patients. Proceed one patient at a time from each one's entry at the initial exam station until he or she leaves through out-processing.
You should be aware that a patient can enter the same department more than once.
(b) Using your simulation data, what are the chances that a patient enters the x-ray department twice?
