<p><strong>Why should questions contain motivation and why does the absence of motivation make questions ambiguous?</strong></p>
<p>I wrote this question <a href="https://stats.stackexchange.com/questions/500094/probability-mass-function-making-the-truncated-normal-discrete">Probability Mass Function making the Truncated Normal Discrete</a> and it was closed because it was ambiguous probably because it lacked motivation.</p>
