AES ENCRYPTION ALGORITHM [closed]

What is the amount of decrease in the probability of decrypting a data encrypted using an AES algorithm? (That is by introducing each round out of ten whole rounds, how the probability of decryption is reduced?)

Why are you asking the same question twice? –  CodesInChaos Mar 26 '13 at 8:34
Sorry, your question as it is is not understandable. Could you try to reword it so it makes some sense? –  Paŭlo Ebermann Mar 27 '13 at 0:03

The probability of decrypting an AES encrypted ciphertext is $1$ if you have the right key and (practically) $0$ if you have the wrong key. This is independent of rounds, key size, ciphertext length, padding, etc.
