2 Conditional Probability and Independence A conditional probability is the probability of one event if another event occurred In the “die-toss” example, the probability of event A, three dots showing, is P(A) = 1 6

Examples: Conditional Probability Definition: If P(F) > 0, then the probability of E given F is defined to be P(EF) = P (E∩F) P (F) Example 1 A machine

Standard results for probability extend to the conditional probability, such that conditional probabilities behave like ordinary probabilities For example, for events A
