There are 9 workers for ASH Development Sdn. Bhd. as shown in Table 24. Unfortunately, there are only 4 rooms available for these workers. Every week, a worker name is randomly selected to do odd jobs for the company. When a worker has been selected randomly, a room needs to be vacated if these rooms are full. Based on Figure Q4, worker's ID number 0 (Umar) is randomly selected for the first week, and the 4 boxes represent 4 rooms for workers.
