title: Laravel 5.6 inRandomOrder and OrderBy
body: <p>How to take datas from Database like this. But randomly and never duplicate.</p>
  
  <pre><code>$questions = Question::orderBy("created_at", 'desc')-&gt;skip(0)-&gt;take(3)-&gt;get();
  $inquiries = Question::orderBy("created_at", 'desc')-&gt;skip(3)-&gt;take(3)-&gt;get();
  $queries = Question::orderBy("created_at", 'desc')-&gt;skip(6)-&gt;take(3)-&gt;get();
  $examinations = Question::orderBy("created_at", 'desc')-&gt;skip(9)-&gt;take(3)-&gt;get();
  $inquisitions = Question::orderBy("created_at", 'desc')-&gt;skip(12)-&gt;take(3)-&gt;get();
  </code></pre>
  
  <p>It works but duplicates.</p>
  
  <pre><code>$questions = Question::inRandomOrder()-&gt;limit(10)-&gt;get();
  $inquiries = Question::inRandomOrder()-&gt;limit(10)-&gt;get();
  $queries = Question::inRandomOrder()-&gt;limit(10)-&gt;get();
  $examinations = Question::inRandomOrder()-&gt;limit(10)-&gt;get();
  $inquisitions = Question::inRandomOrder()-&gt;limit(10)-&gt;get();
  </code></pre>
