The exponential probability distribution is a discrete distribution that is often used to describe time between customer arrivals.

True

Step-by-step explanation:

The time between customer arrivals is called inter-arrival time. According to Queueing Notation, the inter-arrival time can be model based on difference probability distribution. The probability distribution by which the inter-arrival time can be modeled include:

Exponential Distribution or Markov distribution Constant or Deterministic Hyper - exponential Arbitrary or General distribution
