I can't get this question: Call the function by giving an age in the space for a parameter. Tried a few things...

i'm not sure what this question means

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

  <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>

You pass values (arguments) to a function by placing them inside of the parenthesis that follows the function name.

If I had a function named example, then I would pass the number 5 to it like this: example(5). A string would be passed in the same way: example("Hello World"). You can pass multiple arguments by separating them with a comma: example(5, 10).

To complete the third task, you just need to place a number within the parenthesis of the random_age function call.
