1. A bank loan processing system has three components with individual reliabilities as shown below. What is the reliability of the bank loan processing? (Calculate to 3 decimal places) R1 = 0.95 ----> R2 = 0.88 ----> R3 = 0.7

2. An LCD projector in an office has a main light bulb with a reliability of 0.75 and a backup bulb, the reliability of which is 0.9. The system is shown below. What is the reliability of the system? Rbackup = 0.9 | Rprimary = 0.75

3. The following system of components has been proposed for a new product. Determine the reliability of the system. R2 backup = 0.84 | R3 backup = 0.93 | R1 = 0.87 ---> R2 = 0.86 ---> R3 = 0.82 ---> R4 = 0.91
