Conditional probability pmt

In probability theory, conditional probability is a measure of the probability of an event occurring, given that another event (by assumption, presumption, assertion or evidence) has already occurred. This particular method relies on event B occurring with some sort of relationship with another event A. In this event, the event B can be analyzed by a conditional probability with respect t… Webwhich is the same as the probability that a person chosen at random is a woman and a smoker divided by the probability that a person chosen at random is a woman.
