Answer:
This best explains why the best decision alternative is the one with the highest preference probability:
This corresponds to the alternative with the highest probability of getting a good outcome.
Explanation:
In making a decision under probability, it is the decision maker's preference probability that sways the choice. For the decision maker, therefore, the probability of getting a good outcome is always the preferred probability. So, any alternative that yields a good outcome for the decision maker is always chosen. And this usually corresponds to the alternative with the highest preference probability.
