Terms in this set (15)What is the sample space (S)? The sample space S of a chance process is the set of all possible outcomes. What is a probability model? A probability model is a description of some chance process that consists of two parts: a sample space S and a probability for each outcome. What is an event? An event is any collection of outcomes from some chance process. That is, an event is a subset of the sample space. Events are usually designated by capital letters, like A, B, C, and so on. What are the rules of probability models? - The
probability of any event is a number between 0 and 1. When are two events mutually exclusive (disjoint)? Two events are mutually exclusive (disjoint) if they have no outcomes in common and so can never occur together. - Turning left and turning right are Mutually Exclusive (you can't do both at the same time) Complement rule P(AC) = 1 - P(A) How to remember the union and intersection symbols. Hint: To keep the symbols straight, remember ∪ for union and ∩ for intersection. Mutually Exclusive - A and B together is impossible: P(A and B) = 0 - A or B is the sum of A and B: P(A or B) = P(A) + P(B) (Addition rule for mutually exclusive events) How to remember whether unions or intersection have more. "Or has more ... than And" Also ∪ is like a cup which holds more than ∩ Not Mutually Exclusive - A or B is the sum of A and B minus A and B: P(A or B) = P(A) + P(B) − P(A and B) (General Addition Rule for Two Events) What is conditional probability? The probability that one event happens given that another event is already known to have happened is called a conditional probability. Suppose we know that event A has happened. Then the probability that event B happens given that event A has happened is denoted by P(B | A). What does it mean to say that two events are independent? Two events A and B are independent if the occurrence of one event has no effect on the chance that the other event will happen. In other words, events A and B are independent if General multiplication rule The probability that events A and B both occur can be found using the general multiplication
rule Multiplication rule for independent events If A and B are independent events, then the probability that A and B both occur is Conditional probability formula P(B|A) = P(A ∩ B) / P(A).

When two events have no outcomes in common they are called what quizlet?Two events are said to be disjoint or mutually exclusive when they have no outcomes in common.
What happens if the two probability events have no outcomes in common?If there are no outcomes in common, the two events are disjoint.
When two events have no outcomes in common they are called independent events?In probability two events are said to be independent if the occurrence of one event is not affected by the occurrence of another event. Both the variable are completely independent of each other. These events are also known as mutually exclusive event as they have no common point.
