838 Information theory

I just used Answers.com to look up the term "information theory." It reported:

"The theory of the probability of transmission of messages with specified accuracy when the bits of information constituting the messages are subject, with certain probabilities, to transmission failure, distortion, and accidental additions."

Paul's blog (he's a PhD candidate for saving Terri's life) is about information theory. But I'm still confused. If you use "theory" and "probability" in the same sentence, I just black out.

But my oh my, I do love Answers.com.
