Consider our checkout counter example. Assume that there are two types of customers who arrive

according to independent Bernoulli processes with rates $p_{1}in(0,1)$ and $p_{2}in(0,1),$ respectively. The

overall arrival process of all customers follows a merged Bernoulli process of the two separate Bernoulli

processes. All customers who arrive join a single queue, which has a capacity of $10$ customers. We are

interested in making predictions about the length of the queue at any point in time.

For each of the following parts, choose the correct statement.

Assume that service times are not type$-$dependent and are modelled as independent geometric

random variables with parameter qin$(0,1)$ for all customers in the queue.
