| 9227935686 | Disjoint | Events cannot be independent They can be one event or the other but not both and the events have nothing in common with each other. If one has occured the other must not occur. |  | 0 |
| 9228019137 | Independent | One event having occured does not affect the outcome of the other event. (Knowing one has occured does not change the probability of the other occured). P(A and B) = P(A) time P(B). Also P(A) = PA|B) Also P(B) = P(B|A) |  | 1 |
| 9228125544 | Complementary | Not | 2 | |
| 9243011931 | Simulation | The imitation of chance behavior based on a model that accurately reflects the phenomenon under consideration. | 3 | |
| 9243034014 | Probability | The proportion of times an outcome would occur in a very large series of repetitions. | 4 | |
| 9243044996 | Simulation Steps | 1. State the problem 2. State your assumptions regarding probabilities 3. Assign digits to represent outcomes 4. Simulate many repetitions 5. Summarise your findings and state your conclusions. | 5 | |
| 9243068546 | Sample Space | Set of all possible outcomes |  | 6 |
| 9243076044 | Event | Any outcome or set of outcomes. | 7 | |
| 9243088197 | Probability Model | A sample space and a way of assigning probabilities to events. | 8 | |
| 9243143249 | Tree Diagram | A method to show the probability of specific outcomes. |  | 9 |
| 9243180736 | Multiplication principle | n ways times m ways | 10 | |
| 9243225371 | Union (if mutually exclusive) | All possible outcomes A or B A. Juniors B. Seniors | 11 | |
| 9243239125 | Complement | (A^C) All the events not in A A. Juniors | 12 | |
| 9243245482 | Intersection (If independent) | Event consisting of all possible outcomes in both A and B. (AnB) A. Seniors B Females | 13 | |
| 9243264138 | Rules of probability | 1. All probabilities must be between 0 and 1 2. Addition rule: If A and B are disjoint events then P(A or B)= P(A) + P(B) 3. Complement rule: For any event A. P(A^c)=1-P(A) 4. P(S)=1 5. Multiplication rule: If A and B are independent events then P(A and B)=P(A)P(B) | 14 | |
| 9243288176 | Venn Diagram (A and B) |  | 15 | |
| 9245155413 | All probabilities must be.... | between 0 and 1 | 16 | |
| 9245310249 | Addition rule | If A and B are disjoint events then P(A or B)= P(A) + P(B) | 17 | |
| 9245312515 | Complement rule | For any event A. P(A^c)=1-P(A) | 18 | |
| 9256828948 | Multiplication Rule | If A and B are independent events then P(A and B)=P(A)P(B) | 19 |
