A group of students is implementing a simulation for an M/M/2 queue, and their simulated results seem to be different than the theoretical ones. In order to debug the simulator, they check the evolution of the FEL. In the following, we give the snapshot for the FEL list that the students need to debug. The notations used in the FEL are: 1 - arrival event 2 - departure event for server 1 3 - departure event for server 2 system state = (no in queue, server 1 (busy or idle), server 2 (busy or idle)) event scheduled in FEL: (type, time) Find the errors reflected in the FEL
