The pharmacist at Arnold Palmer$$ Hospital, Wende$$ Huehn$-$Brown, receives $15$ requests for prescriptions each$$ hour, Poisson distributed. It takes her a mean time of $3$ minutes to fill$$ each, following a negative exponential distribution. The waiting line table is provided below and also we know that Wq$=$Lq$\backslash$lambda $.$
