title: How to addClass() at RANDOM to an element in jQuery?
body: <p>The html/css:</p>
  
  <pre><code>&lt;style&gt;
  div.myWords p { display: hidden; }
  p.show { display: block; }
  &lt;/style&gt;
  
  &lt;div class="myWords"&gt;
  
  &lt;p&gt;Hello&lt;/p&gt;
  &lt;p&gt;Hola&lt;/p&gt;
  &lt;p&gt;Bonjour&lt;/p&gt;
  
  &lt;/div&gt;&lt;!-- myWords --&gt;
  </code></pre>
  
  <p>How can I add the class "show" to a single <code>&lt;p&gt;</code> element at a time at random on document ready?</p>
  
  <p>In other words, every time the page is loaded 1 p tag should be visible and this p tag should be chosen at random.</p>
