According to the subjective, or personal, interpretation of probability, the probability that a person assign to a possible outcome of some process represents her own judgment of the likelihood that the outcome will be obtained. This judgment will be based on each person’s beliefs and information about the process. Another person, may have different beliefs or different information, may assign a different probability to the same outcome. For this reason, it is appropriate to speak of a certain person’s subjective probability of an outcome, rather than to speak of the true probability of the outcome.
