(d) How long is the queue at this point? 8 (= Cum. Arrival – Cum. Departure = λ * 42 -μ∗12 = 14 − 6 = 8) (e) How long will you have to wait before being served? 16 min (at this moment, 8 people are in front of you. Since serving 1 person requires 1/ μ = 2 min, so, you need to wait for 8*2 = 16 min) (f) How many people will have been served by 10:00? 30 (= Cum Departure)- End of Paper -...
