Solution
Probability of an event = frequency of that event occurring/ Total number of events
a. probability of the fatality resulting from fall = 645/4535 = 0.1422 or 14.22%
b. probability of the fatality resulting from a transporation incident = 1795/4535 = 0.3958 or 39.58%
c. least cause of fatality is Fires and explosions(113)
probability = 113/4535 =0.0249 or 2.49%
| Cause | Number |
| Transportation Incidents | 1795 |
| Assaults and violent acts | 837 |
| Contacts with objects and equipment | 741 |
| Falls | 645 |
| Exposure to harmful substances | 404 |
| Fires and explosions | 113 |
| TOTAL | 4535 |
