How to create random number every minute : <p>I have a question.
"random number of customers arriving for a check out is between 5 and 10 every minute."
 I need to put these customers in a list based on their order of their arrival time. </p>

<p>I don't know how to generate a random numbers of customers every minute, and I don't know how to assume their arrival time. </p>
