Question
A certain factory operates three different shifts. Over the last year, 200 accidents have occurred at the factory. Some of
these can be attributed at least in part to unsafe working conditions, whereas the others are unrelated to working
conditions. The accompanying table gives the percentage of accidents falling in each type of accident-shift category.

Suppose one of the 200 accident reports is randomly selected from a file of reports, and the shift and type of accident are
determined.
(a) What are the simple events? (Let S,, S, and S3 represent the day, swing, and night shifts, respectively. Let C,
and C, represent the unsafe conditions and unrelated to conditions, respectively. Enter your answer in set notation.)
(b) What is the probability that the selected accident was attributed to unsafe conditions?
(c) What is the probability that the selected accident did not occur on the day shift?
