Question 415759: In 1984 an internal investigation within major New York metropolitan hospital was
leaked to the New York Herald. The investigation found that on average out of every 125
medications dispensed there were 2 errors, but only 1 in 500 medications dispensed
significantly harmed the patient. Of those suffering significant harm from medication
error, 2% died. The hospital at that time dispensed 75,000 medications during the year
of this investigation.
a. What was the expected number of significant errors?
b. How many died as a result from hospital medication errors? How many are
expected to have died after a medication error?
c. Out of all medication errors, what is the expected percentage that would result
in death?

b. How many died as a result from hospital medication errors? How many are
expected to have died after a medication error?
Ans: 0.02*1200 = 24
