A two-server queueing system is in a steady-state condition

and the steady state probabilities are p0 = 1

16 ; p1 = 4

16 ; p2 = 6

16 ; p3 =

4

16 ; p4 = 1

16 ; pn = 0 if n > 4. Calculate

1. L (the expected number of customers in the system) and Lq

(the expected number of customers in the queue)
