C.
Interpretation: The probability about the system being empty needs to be computed.
Concept Introduction:

D.
Interpretation: The probability about the queue being empty needs to be computed.
Concept Introduction:
Probability: Probability is the chance of an event occurring. Number of favorable outcomes must be divided by total number of possible outcomes to get the probability factor.
e.
Interpretation: The probability about the flow time exceeding 10 minutes needs to be computed.
Concept Introduction:
Probability: Probability is the chance of an event occurring. Number of favorable outcomes must be divided by total number of possible outcomes to get the probability factor.
