The emergency department (ed) in the middletown general hospital sees about 200 patients each day. on average, 150 of these are discharged to home after being seen; but about 50 of the patients seen need to stay overnight in a hospital bed. about 20 percent of these are on "observation" status, meaning that an admission decision has not yet been made, pending some test results or the result of an overnight observation stay. the remaining 80 percent are admitted directly. currently all patients who stay overnight (whether admitted or on observation status) are put into an inpatient bed . that is, there is no separate observation area in which patients can be boarded. if 80 percent of observation patients are discharged to home, and 20 percent are upgraded to inpatient status (and these then stay an average of 5.8 days), what is the average census of admitted patients in the hospital? if there are 270 inpatient beds in middletown general, what is the utilization of the beds (occupancy rate in percentage of beds filled)? (hint: the flow of admitted patients will be those admitted directly from the ed plus those admitted from observation status, and both of these stay an average 5.8 days.)

Alarge but sparsely populated county has two small hospitals, one at the south end of the county and the other at the north end. the south hospital's emergency room has four beds, whereas the north hospital's emergency room has only three beds. let x denote the number of south beds occupied at a particular time on a given day, and let y denote the number of north beds occupied at the same time on the same day. suppose that these two rv's are independent; that the pmf of x puts probability masses 0.2, 0.2, 0.1, 0.2, and 0.3 on the x values 0, 1, 2, 3, and 4, respectively; and that the pmf of y distributes probabilities 0.3, 0.2, 0.1, and 0.4 on the y values 0, 1, 2, and 3, respectively. a. display the joint pmf of x and yin a joint probability table. b. compute p(x< =1 and y< =1) by adding probabilities from the joint pmf, and verify that this equals the product of p(x< =1) and p(y< =1). c. express the event that the total number of beds occupied at the two hospitals combined is at most 1 in terms of x and y and then calculate this probability. d. what is the probability that at least one of the two hospitals has no beds occupied?
