Chapter 4 Part4 General Probability Rules Download now. download to read offline. this document discusses basic concepts of probability, including: the addition rule and multiplication rule for calculating probabilities of compound events. events can be disjoint (mutually exclusive) or not disjoint. the probability of an event occurring or its complement must equal 1. Rule 1: the probability of an impossible event is zero; the probability of a certain event is one. therefore, for any event a, the range of possible probabilities is: 0 ≤ p (a) ≤ 1. rule 2: for s the sample space of all possibilities, p (s) = 1. that is the sum of all the probabilities for all possible events is equal to one.

Ch4: probability and counting rules santorico – page 105 event – consists of a set of possible outcomes of a probability experiment. can be one outcome or more than one outcome. simple event – an event with one outcome. compound event – an event with more than one outcome. example: roll a die and get a 6 (simple event). In the addition rule, the word “or” in p(a or b) suggests addition. add p(a) and p(b), being careful to add in such a way that every outcome is counted only once. in the multiplication rule, the word “and” in p(a and b) suggests multiplication. multiply p(a) and p(b), but be sure that the probability of event b takes into. Learning objectives. 1. the multiplication rule (and) calculate the probability of two independent events both occurring together. 2. the addition rule (or) calculate the probability of two mutually exclusive events. calculate the probability of two events that are not mutually exclusive. when calculating probability, there are two rules to.

Rule 4. complement rule: for any event a, p (ac) = 1 − p (a) rule 5. multiplication rule: if a and b are independent events, then. p (a and b) = p (a) p (b) general addition rules. probability has the property that if a and b are disjoint events, then p (a or b) = p (a) p (b).
