  <p id = "P1"></p>
  <p id = "P2"></p>
  <p id = "P3"></p>
  <p id = "P4"></p>
  <script>
    document.getElementById("P1").innerHTML = Math.random();
    document.getElementById("P2").innerHTML = Math.random();
    document.getElementById("P3").innerHTML = Math.random();
    document.getElementById("P4").innerHTML = Math.random();
