My question goes as below:

A major warehouse facility has 10 semi-trailer loading bays, which can all be used simultaneously. On average only 7 bays are in use.

a. What is the probability that all bays will be in simultaneous use.

b. What is the probability that one or more semi-trailers will have to wait for a bay to become available.

c. Show a loading bay demand for zero to fifteen semitrailers.

Please suggest which distribution Binomial or Poisson to use for this question?

Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking. See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help center, please edit the question.

  • $\begingroup$ There isn't enough information given to answer this question: you will need to make some additional assumptions. An example is you might want to assume all bays are equally likely to be used and usage of one bay is independent of usage of any other bay. For (b) and (c) you will need to assume some kind of stochastic process for the arrivals of semitrailers. $\endgroup$ – whuber May 24 at 14:03
