A product is made up of two subsystems in parallel. The first subsystem

consists of 50 components in series. The second subsystem consists of 30

components in series. The components in subsystem 1 are all of the same

design and each has a 5/1000 chance of failure. The components in subsystem

2 are also of the same design and each has a 8/1000 chance for failure. What is

the overall reliability of the system?

RS= 1- (0.221687)(0.214131)

Please create a process map for withdrawing cash from an ATM machine as

described below:

Janet needed some cash and walks up to an ATM machine. She inserts her debit

card. The machine returns the card and the monitor reads: “could not read the

card try again”. Janet recognizes that she has entered the card in the wrong

direction. She takes the card and turns it around and insert the card again. The

machine keeps the card and the monitor reads: “enter pass code”. Janet enters

a 4 digit code. The monitor reads: “ error, try again”.

Janet enters the code again. The monitor displays: Withdrawal? Yes No

Janet selects Yes. Displays shows:

“ $100, $200, $300, $400, $______”.

Janet selects $200. The machine pushes out 10 $20 bills. Monitor then

displays “Receipt? Yes No”. Janet selects No. Monitor displays “Take your

cash” .
