| 5369599837 | Probability | A number between 0 and 1 that reports the likelihood of the event's occurrence. | 0 | |
| 5369599838 | Trial | A single attempt | 1 | |
| 5369599839 | Outcome | Value measured, observed, or reported for an individual instance of the trial | 2 | |
| 5369599840 | Event | A collection of outcomes | 3 | |
| 5369599841 | Independence | If knowing whether one event occurs does not alter the probability that the other event occurs. | 4 | |
| 5369599842 | Law of Large Numbers | Long-run relative frequency of repeated independent events becomes close to actual frequency as number of trials increases. | 5 | |
| 5369599843 | Complement Rule | 1 minus the probability that it doesn't occur | 6 | |
| 5369599844 | Disjoint (Mutually Exclusive) | They share no outcomes in common. | 7 | |
| 5369599846 | General Addition Rule | P(A U B) = P(A) + P(B) - P(A intersect B) | 8 | |
| 5369599847 | Multiplication Rule of Independent Events | P(A intersect B) = P(A) * P(B) | 9 | |
| 5369599848 | Sample Space | The collection of all possible outcome values | 10 | |
| 5369599849 | Conditional Probability | P(B | A) = P(A intersect B)/P(A) | 11 | |
| 5369599850 | Formal Independence | P(B|A) = P(B) | 12 | |
| 5369859882 | Disjoint (Mutually Exclusive) and independence | Disjoint events can't be independent because they have no outcomes in common-> knowing that one event occurred means that the other didn't. | 13 |
