A two-server queueing system is in a steady-state condition and the steadystate probabilities are P0 =1/16 , P1 =1/4, P2 =3/8, P3 =1/4, P4 =1/16 , and Pn = 0
if n > 4. The mean arrival rates are λ0 = 8, λ1 = 4, λ2 = 2, λ3 = 1, and
λn = 0 if n > 3. Find
(i) the expected number of customers in the queue,
(ii) the expected number of customers being served,
(iii) the expected waiting time in the queue per customer, and
(iv) the expected service time per customer.

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
