Well, let's see. There's

Math.random(), which will give you a random number between 0 (inclusive) and 1 (exclusive)
window.location, a property to which you can assign a URL to take the browser to a new page
Arrays, which can contain strings, which can be URLs

Put them together, and you have the ability to pick a URL at random (from the array, using Math.random) and tell the browser to go there.

To build on T.J.'s answer, there is one potentially tricky bit remaining: converting a random decimal (from Math.random()) to a random index. You can get that with min + Math.floor(Math.random() * (max - min + 1))
