How do I find intrinsic value of a stock using the numbers from Yahoo finances?

Is this for a class? If so, there is no one method to figure an intrinsic value of a stock and you would have to utilize the method used by your book. So if it's for that purpose, you're going to have to look it up there. If you don't understand the equation, then ask about it specifically.

The intrinsic value can be personal, based on what its worth to you is. My finance book uses what they call an average ("expected value") and they have a specific equation they're using for it, but there's no way I could copy that equation here.

Here are a couple of links to ways of figuring this out, but I don't know how much sense they're going to make:
