How does selecting Chance is applied to duration unit option work?

During a simulation the chance the risk can occur either as a function of the duration of a task or the duration unit in which the task is measured. For example a task can be 10 days in length. The chance that a risk will occur could apply to the 10 duration, or it could be that the risk could have the chance of occurring each day at the set %. The difference in this case is that if the chance is for the entire task, during a simulation that risk can only occur once during that task. However, if the chance is applied to the duration unit, in this case days, the risk could occur multiple times during the activity. So the actual calculated probability of the risk occurring can be much higher.

As commonly understood, the chance of a risk occurring is seen as over the entire duration of an activity; therefore, this is the default setting. However, there could be cases, especially on longer activities where applying the chance to duration units may be applicable.
