Stochastic Processes 1. Let {Xt;t > 0} be a pure birth process with rate 1x > 0, for x ES = {0,1,2,...}. (a) Write the backward equations (KBE) and use it to solve for Pxx(1).
Let X = the time between two successive arrivals (in minutes) at a drive thru window. Suppose X is exponentially distributed, and that the average time between successive arrivals at the drive thru window is 1.2 minutes. What is the value of lambda, the parameter of exponential distribution? What is the probability that the next drive thru arrival is between 1 to 4 minutes from now? What is the probability that the next drive thru arrival is greater than 2...

2. Arrivals to Chipotle follow a nonhomogeneous Poisson process with rate function λ(t) = 50 arrivals per minute for the first ten minutes after 11:30 a.m (t0 corresponds 0 and t 4 and there 2+1/5 t2/ to 11:30). Find the probability that there are 3 arrivals between are three arrivals between t = 3 and t = 6. 2.

4. Arrivals of passengers at a bus stop form a Poisson process X(t) with rate ? = 2 per unit time. Assume that a bus departed at timet 0 leaving no customers behind. Let T denote the arrival time of the next bus. Then, the number of passengers present when it arrives is X(T) Suppose that the bus arrival time T is independent of the Poisson process and that T has the uniform probability density function 1,for 0t1, 0 ,elsewhere...
