B. Talk with patient about preexisting health problems, which is90s.
C. Doing the surgery, which takes 180s or 3 minutes, again onaverage exponential distribution.
D. Patient, post operation, will rest immobile for 30seconds.

Each step can at most have 1 patient ata time. In a 120 minutes, how many patients can the clinic helpoperate? (2 hours). 20 marks/100 - Show your work.
