Consider a single-server first-come, first-served queueing system where the maximum number of customersin the system is 4(including the customer in service).

Now consider the following exception: When there are 4 customers in the system, the server works 50% faster, but otherwise works at the service rate stated above. Re-compute the fraction of customers that are denied service because the system is full.
