Hi, does anyone know how to model probability density function, b(x), of a system that has two parallel servers:(adsbygoogle = window.adsbygoogle || []).push({});

-The first is selected by the customer with probability [itex]p[/itex], it has an exponential rate of [itex]\mu[/itex].

-The second server is selected by the customer with probability [itex]1-p[/itex], it has a deterministic rate of [itex]k[/itex].

-When a customer chooses a server, another servers waits until the customer being served leaves.

If the second server were an exponential rate server, it would simply be an M/Er=2/1 system but now I don't know how to model this. Can anyone help me, plz?
