Please provide clear math/reasons to get the answer

Consider the following four-step assembly operation with quality problems. All resources are staffed by one employee.

The first resource has a processing time of 5 minutes per unit.

The second resource has a processing time of 6 minutes per unit.

The third resource has a processing time of 3 minutes per unit. With a 30 percent probability, the flow unit coming out of the third resource has to be reworked. In that case, the operations at the first, second, and third resources are repeated. You can assume that (a) rework always succeeds and (b) the processing times for units in rework are same as for regular units.

The fourth resource has a processing time of 4 minutes per unit.

Where in this process is the bottleneck? What is the capacity of the process?
