How to randomize the order that functions are run?

I know there is a better way to do this. Any ideas?

randomRadio = Math.round(Math.random() * 4);
    if (randomRadio === 4) {
        createRadios("d");
        createRadios("c");
        createRadios("b");
        createRadios("a");
    } else if (randomRadio === 3) {
        createRadios("c");
        createRadios("a");
        createRadios("b");
        createRadios("d");
    } else if (randomRadio === 2) {
        createRadios("a");
        createRadios("b");
        createRadios("c");
        createRadios("d");
    } else {
        createRadios("b");
        createRadios("a");
        createRadios("c");
        createRadios("d");
    }

My suggestion:

Add all function to an array, something like this:

var rArray = ["a", "b", "c", "d"];

Then shuffle the array

function shuffle(array) {
  var currentIndex = array.length, temporaryValue, randomIndex ;

  // While there remain elements to shuffle...
  while (0 !== currentIndex) {

    // Pick a remaining element...
    randomIndex = Math.floor(Math.random() * currentIndex);
    currentIndex -= 1;

    // And swap it with the current element.
    temporaryValue = array[currentIndex];
    array[currentIndex] = array[randomIndex];
    array[randomIndex] = temporaryValue;
  }

  return array;
}

And finally do a for loop passing the array order to the createRadio function
