title: Generate a exponential distribution with lambda=3
body: <p>I have an assignment and now got confused about exponential distribution. The instructions say &quot;service time is exponential distributed with intensity <code>lambda = 3</code>.&quot;</p>
  <p>First I thought generating this is just <code>exp(3)</code>, but using Matlab I am wondering if this is right interpretation of the text. Maybe I should use <code>exprnd(3)</code> instead?</p>
