Statistics Queue problem: M/M/2

[caliboy]

Homework Statement

OK I am dealing with a Queue type problem that is M/M/2. I have already solved most of the problem but I can not figure out how to solve for ∏₀, L_q, L, & W.
The information I am given is: λ=11.98, μ=7 and s=2.

Homework Equations

The Attempt at a Solution

I am trying to figure out how the book i am using solved the problem. The book does not demonstrate how to solve this type of queieing problem?? I do have the answers for everything I am looking for, just do not know how to find them.
p=.8557, π₀=.2826, L_q=0.13527, L=1.8467, W=0.1541

Any help with formulas to use in solving this problem will be greatly appreciated.

You are supposed to show your work. What have you done so far? Where are you stuck? That is: exactly what does the question say, what parts have you already done, and what did you get?
