A professor needs to go to a clinic to get an MRI for his upcoming craniectomy and is worried about how long it will take. First, there is the wait time, which is normally distributed. Then there is the MRI, a procedure whose time depends on what the MRI technician finds and increases in increments of

10 minutes (because it involves pre-programmed modules). The table below summarizes the distributions for waiting times and MRI procedure times.

Waiting (Minutes) m s		MRI (Minutes) Minutes Probability
60	15	30	0.1
(NORMAL DIST.)		40	0.25
		50	0.35
		60	0.2
		70	0.1

What is the average total time spent in the clinic? (Use 10,000 trials)
