Conditional probability is a measure of the likelihood of an event occurring given that another event has already occurred. It is denoted as \\( P(A | B) \\), which reads "the probability of event A given event B." Mathematically, conditional probability can be defined using the formula: \\\[ P(A | B) = \\frac\{P(A \\cap B)\}\{P(B)\} \\\] provided that \\( P(B) > 0 \\).
