Please do the questions with handwritten working. I'm struggling to understand what to write XA=2. In a large company, two separate Poisson surplus processes are beingmonitored. In process A, reserves of UA = 3000 are available, approx-imately 25 claims are expected annually, A = 0.20, and thetypical claim XA is a (0.75, 0.25) mixture of an exponential randomvariable with mean = 60 and an exponential with mean µ = 20. Forprocess B, UB 1000, AB 30, B = 0.20 and XB = 50. For both ofthese processes, find the adjustment coefficient of the process and com-ment on the differences. Using Lundberg's inequality, determine upperbounds on the probabilities of ruin for the two processes.==

Structures in a county need to be designed for earthquake loading. After a detailed seismic risk analysis of the county, it is observed that the peak ground acceleration A observed in an earthquake event can be modeled by an exponential distribution with a mean of 0.2g. If A exceeds 0.4g, structures in the county will suffer significant damage. Assume that earthquakes occur on the average once every 2 years in the county, and the damage from different earthquakes is statistically independent. (a) What is the probability that there will be exactly two earthquakes in the next 50 years? (b) What is the probability of significant structural damage in an earthquake? (c) What is the probability of no significant structural damage due to earthquakes in a year? (d) What is the probability of no significant structural damage due to earthquakes in the next 50 years?

A production plant has three machines and the two products move about among these three machines. Upon completion of the process at machine i, it moves to the next available machine out of the two remaining machines. Therefore, there are always two busy machines.

A hospital has two operation rooms. The service times for each of them is exponentially distributed with mean 17 minutes and are supposed to be independent. When both operation rooms are not busy then Akbar arrives. Whereas Bilal arrives 12 minutes later while Akbar is still under medication.After another 20 minutes later, Sameer arrives and both Akbar and Bilal are still under the medical treatment. There is no other arrival of any patient during this 40-minute time period.(a). Find the probability that Akbar will be ready before the Bilal’s arrival?(b). Find the probability that Sameer will be ready before Bilal’s arrival?(c). Find the probability that Sameer will be ready before Bilal’s arrival?(d). Calculate the waiting time for Sameer in the system?
