Create a Simio model for the following process. Customers arrive to a bank teller window at a rate of $6$per hour, time between arrivals is exponential. The amount of time required for service is exponentiallydistributed with a mean of $6$ minutes. There is one bank teller. Bank open $9$am$5$pm$.$ The bank tellerbegins the day with $$2000\mathrm{.}00.$ Customer either wants a deposit or withdrawal. The amount oftransaction follows normal distribution with mean of $0$ and standard deviation of $$500\mathrm{.}00.$ All depositsare taken. If withdrawal is requested and cannot be met, the bank fails.

$(1)$ Estimate the probability that bank fails

$(2)$ Average amount of cash left at the end of days when bank does not fail
