Javascript inline HTML

I need to write HTML and Javascript code inline i.e. inside HTML Body (Need to display some random whole number value) I sought a lot of blogs but found no help so far in doing so. Please advise.

I wanna achieve this functionality:

   <td class="vhead">Offered Calls</td>
   <td>
      <script>
       Math.random();
      </script>
  </td>
  </td>
