WebSep 5, 2024 · Conditional Probability. The conditional probability concept is one of the most fundamental in probability theory and in my opinion is a trickier type of probability. It defines the probability of one event occurring given that another event has occurred (by assumption, presumption, assertion or evidence). 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.
