I checked this forum for any potential help with stochastic processes. I hope there is anybody who could help me with a couple of homework questions/tasks. I would very much appreciate any help and would also be willing to compensate. I need to provide solutions for the following questions: 1. Variable x has four values: 0,31; 0,49; 0,01 and 0,45. Can x be uniformly distributed? Elaborate. 2. It takes one minute to buy a ticket. On average, two buyers enter the queue in three minutes. Find the average length of the queue and the probability that there is one person in the queue. The time it takes to serve a person is distributes exponentially and a single server mode is studied. 3. The probability of equipment stopping abruptly, during one minute, is 0,2. Service person checks equipment once in every minute. There is a 0,6 probability that equipment, that has stopped, is going to be fixed within one minute. Find the probability that equipment is still working after two minutes, if it was working at the outset. I have the related book (Basic textbook : H.A.Taha, Operations Research: An Introduction, Prentice Hall) as pdffile, if required. Thanks in advance. Kind regards Tom

I have to check whether I find the appropriate link again. I can also email the book otherwise. Do you think you can solve the questions ? Or do you know anybody who does ? Thank you Tom
