Thus the union sample space would be {2, 4, 5, 6} Notice we did NOT write the “4” or “6” twice. Conditional Probability: Conditional probability is the probability that an event occurs given that another event has already occurred. Keeping with the two events we get an even number {2, 4, 6} or greater than 3 which is {4, 5, 6}.

"The probability of the union of two events is equal to the sum of their probabilities less the probability of their intersection." P(A | B) = P(A ( B) / P(B) "A conditional probability is equal to the probability of the intersection of the two events divided by the probability of the condition." (B, the event after the "bar," is …

Probability of a Union of Two Events: P(A U B) = P(A) + P(B) – P(A ∩ B) What is the probability that it will be rated “Good” in useful life or intensity? Complementary Events. The complement of an event A (denoted ) is the collection of outcomes that do not correspond to A.

Probability . The probability of an event, A, denoted as P( A ), is a quantity to describe how likely event A occurs. Ex. P( A ) = 0 Event A will never occur. Axiom of probability. The probability of any event must lie between 0 and 1. That is, for any event A, 2. The total probability assigned to the sample space of an experiment must be 1.
