The real justification for regarding the entropy as the amount of information is that, unsightly though it is, though it's abstracted away all the content of the message and almost all of the context except for the distribution over messages , it works.
You can try to design a communication channel which doesn't respect the theorems of information theory; in fact, people did; you'll fail, as they did. Of course, nothing really depends on guessing the contents of sealed envelopes; any sort of random variable will do.
The next natural extension is to say, "Well, I've got two envelopes here, and I want to know what all the messages are in both of them; how many questions will that take?
The case of more than two is a pretty simple extension, left to the reader's ingenuity and bored afternoons. But some combinations of messages may be more likely than others.
If one of them is "Marry me? Hence "mutual.
I should now talk about the source and channel coding theorems, and error-correcting codes, which are remarkably counter-intuitive beasts, but I don't feel up to it. I should also talk about the connection to Kolmogorov complexity, too.
Kevin Buckley, Tolentine a, W , F , buckley ece. Grading Policy: This course covers information theory and coding within the context of modern digital communications applications. We begin with a directed review of probability and digital modulation schemes.
Source coding is considered because it provides a straightforward example of the utility entropy, an information theory measure. Channel coding is considered because channel capacity, another information theory measure, provides a theoretical bound which is the goal of channel coding.
We then proceed with an in depth treatment of block and convolutional channel coding, with both soft and hard decoding. Bit-error-rate performance is studied relative to channel capacity.
Advanced topics such as Reed-Solomon codes, space time codes, concatenated codes, turbo coding and LDPC codes are introduced. ECE Course Notes Sections [8.

A less probable event is rarer and so it contains more information. Thus, if n event of lower probability occurs, it conveys more information than occurrence of an event of larger probability. Entropy Average information: Suppose there are m different msg m1, m2, m3, …….
If L is very large then we can say that msg of m are transmitted.
