Project Implementation And Management Practice Test

How is probability best defined in risk terminology?

Severity: the impact of the risk on the project. Frequency: the number of times a risk can impact the project. Hazard: a rare and extreme event that may affect project outcomes. Probability: degree to which the risk event is likely to occur.

Correct Answer:

Probability: degree to which the risk event is likely to occur.

Explanation:

Probability is the degree to which a risk event is likely to occur. It measures likelihood of the event happening, not its impact or how often it could happen. In risk management, this is used alongside severity (the impact if it occurs) to assess overall risk exposure: risk exposure = probability × impact. For example, a risk with high impact but low probability may be less threatening than one with moderate impact and high probability. The other terms describe different ideas: severity is about consequence, frequency concerns how often something might occur, and hazard is a condition that could cause harm but does not itself quantify likelihood.
