We consider two independent copies fX1(t); t 0g and fX2(t); t 0g of this process, and we define Y (t) = jX1(t) X2(t)j for t 0 We can show that fY (t); t 0g is also a birth and death process. a) Give the birth and death rates of the process fY (t); t 0g. b) Calculate the expected value of the random variable Y (t) after two transitions if X1(0) = X2(0) = 0 c) Calculate the limiting probabilities of the processes fY (t); t 0g.

Ineed with 14, 16, 28 and 36 me. we didn't go over them in class so i don't know what to do.

Saline iv fluid bags cost $64.20 for 24, 1000 ml bags from one supplier. a new supplier sells 500 ml bags for $2 each. the hospital uses about 10,000, 1000 ml bags each month. nurses report that about half of the bags are more than half full when they are discarded. if you are going to use only one supplier, which size bag provides the best deal, and how much will you save each month? compare the cost of the new supplier to the current one.
