Activity durations of three projects, Project A$,$ Project B$,$ and Project C$,$ are estimated by the three$-$point estimate. That is$,$ the three numbers under each task are three$-$point estimates of activity duration: Optimistic, Most likely, and Pessimistic estimates. The unit is "day".

If the target duration of the projects is equally $19$ days, which of the following is a CORRECT description of the schedule delay risk that a project actually takes more than the target duration, $19$ days?
