An alternative name for probability. The risk of an event occurring is the probability of the event occurring and is mainly used when the event is related to a health issue or is an undesirable event.
Example
The following data were collected on a random sample of students enrolled in a Statistics course at the University of Auckland.
| Attendance | ||||
| Regular | Not regular | Total | ||
| Course result |
Pass Fail |
83 17 |
19 27 |
102 44 |
| Total | 100 | 46 | 146 |
Based on this sample of students, the risk of failing = 44/146 = 0.30
The risk of failing for students with regular attendance = 17/100 = 0.17
