WebDec 21, 2024 · The probability of one event given the presence of another event is called the conditional probability and it can be calculated using the following formula: P(A given B) = P(A and B) / P(B) Here, we can take event A as “2 boys” and event B as “oldest is a boy”. A = “2 boys” B = “oldest is a boy” WebConditional Probability. The conditional probability, as its name suggests, is the probability of happening an event that is based upon a condition.For example, assume that the probability of a boy playing …

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.
