Combinations of Events: Union, Intersection, complement, disjoint . Consider the fuses example: let B denote the event that at most one fuse fails inspection. What is ?? A’? B’? Are events A and B disjoint? A = B = It is often useful to use Venn diagram to visualize the relationships between events (1) , the union of events A and B. It ...

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.

Perform a simulation of a probability problem using a table of random numbers or technology. Use the basic rules of probability to solve probability problems. Write out the sample space for a probability random phenomenon, and use it to answer probability questions. Describe what is meant by the intersection and union of two events.

The sum of the probabilities in a probability distribution can be any number between 0 and 1. II. The probability of the union of two events is the sum of the probabilities of those events. III. The probability that an event happens is equal to 1 – (the probability that the event does not happen).

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}.

Probability of Union of Two Mutually Exclusive Events. If two events A and B are mutually exclusive, the probability of the union of A and B equals the sum of the probabilities of A and B; that is, P() =P(A) + P(B) Please look at Example 3.14 at page 141 in our textbook. Conditional Probability. The new notation is a conditional probability.

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 ...
