I have only recently started studying information theory and I am stuck even trying to understand the basic problem and concept of information theory. My question is why does information need a probability?
I have read some text that starts by introducing the idea that the amount of information is determined by how many states a system can have. This is intuitive but it then goes on to say that the information content is more precisely related to the probability of occurence of a particular state. This doesn't make any sense to me and I cannot see why probability is introduced at all.
