comment Distinguishable balls in distinguishable boxes?
Still impossible to understand. For one thing, the new formula does not depend on $k$. Have you tried to study a particular example, with small $N,n$?

comment determine how much probability increase with an added condition
Now, if the events $E_i$ is "the person $i$ got a valuable prize", then the events are not exclusive at all, so the probablities $p_i = P(E_i)$ don't sum 1.

comment determine how much probability increase with an added condition
Doesn't "he pick one prize randomly" and "people will get more chance to win the valuable prize if they know what among them are actually valuable in advance" contradict? They pick the prizes randomly, or they have freedom to choose? Further: "the expected probability each person can get the valuable prize" is confusing. First, you should either speak of "probability" (of an event) or "expectation" (of a random variable). I guess it's the first here (you should remove "expected", then).

comment Distinguishable balls in distinguishable boxes?
The statement is not clear to me. Isn't your description of a valid configuration equivalent of saying : "put $n$ balls in $N$ boxes such that (at least) one box has exactly $k$ balls" ?

Of course. But, again, it dependends on the time.

comment Can this be a Markov Chain?
Well, as non-stationary. Or "time-inhomogeneous". Truth to be told, these ones are less studied and used. In your particular case, I doubt that it would be practical/useful to model that as a Markov Chain.
