Toxic chemical incidents. Process Safety Progress (Sept. 2004) reported on an emergency response system for incidents involving toxic chemicals in Taiwan. The system has logged over 250 incidents since being implemented. The next table gives a breakdown of the locations where these incidents occurred. Consider the location of a toxic chemical incident in Taiwan.
a List the sample points for this experiment.
b Assign reasonable probabilities to the sample points.
c What is the probability that the incident occurs in a school laboratory?
d What is the probability that the incident occurs in either a chemical or a nonchemical plant?
e What is the probability that the incident does not occur in transit?
Location | Percent of Incidents |
School laboratory | 6% |
In transit | 26% |
Chemical plant | 21% |
Nonchemical plant | 35% |
Other | 12% |
Total | 100% |
