Thank you for your answer. Since it was already stated in the question that all five actions have been carried out before and the utility values are known, I thought the player would only exploit a particular action with the highest utility value.
But I understand your point about coming back to state 27 via other actions with "better" utility values which would then affect the actions being taken from state 27.
Thank you for your response. And no, this is directly from a test which unfortunately I don't have the memo to cross-check my answers.
