1. New information obtained through research or experimentation that enables an updating or revision of the state-of-nature probabilities is known as
conditional probability.
joint probability.
sample information.
expected utility.
2.__________ refer to the probabilities of the states of nature after revising the prior probabilities based on sample information.
Preliminary probabilities
Joint probabilities
Posterior probabilities
Perfect probabilities
3._____ refers to the probability of one event, given the known outcome of a (possibly) related event.
Joint probability
Decisive probability
Conditional probability
A priori probability
4.Bayes’ theorem
enables the use of sample information to revise prior probabilities.
is useful for determining optimal decisions without requiring knowledge of probabilities of the states of nature.
can be used only for cases where conditional probabilities are unknown.
cannot be used to calculate posterior probabilities.
