Hello,
You should also compute the probabilities for each outcome when Alice makes her measurement.
Dont be disturbed by the phrasing in the question. By analyze standard teleportation protocol i just mean that Alice and Bob proceed just as in the protocol shown in class (they dont know the initial entanglement link is corrupted).
Indeed at the very end Bob gets states with extra terms wrt the ideal case. The probabilities will also not be exactly equal to 1/4.
Hope this answers your questions
