Suppose you have a three task sequence. All customers go to Task A. After task A, 60% of customers go to Task B; the other 40% go to task C. After task B or C, all customers then go to Task D before leaving. No buffers exist between tasks, so blocking/starvation rules apply.

Suppose throughput capacities are as follows. Task A: 10 customers/hour; task B: 5 customers/hour; task C: 6 customers/hour; task D, 12 customers/hour.

Use this information to answer the next 3 questions.

At what rate will customers leave task D (in customers/hour)? Pick the closest answer.
