Calling a function?

What is calling a function? In the (parantesses) I've tried (num) and even (21). Neither worked.

script.js 
function random_age(age) {
  Math.floor(Math.random() * age);
}
random_age();
index.html 
<!DOCTYPE html>

  <head>
    <meta charset="utf-8">

    <link href="normalize.css" rel="stylesheet">
    <link href="style.css" rel="stylesheet">
  </head>
  <body>
    <h1 class="logo"><img src="img/mash-logo.svg" /></h1>
    <p class="instructions">Fill in the blanks and your future will be foretold.</p>
    <form action="" method="post" id="mash">
      <div class="choice-bucket">
        <h4 class="highlight">What's your future pet?</h4>
        <input name="pet[]">
        <input name="pet[]">
        <input name="pet[]">
        <input name="pet[]">
      </div>
      <input type="submit" value="Tell my fortune">
    </form>

    <script src="script.js"></script>

  </body>
</html>

If what you mean is that you tried: 

random_age(21);

then you did fine, that should work! :) Unless you changed something else.
