Problem 16-05 (Algorithmic)
A major traffic problem in the Greater Cincinnati area involves
traffic attempting to cross the Ohio River from Cincinnati to
Kentucky using Interstate 75. Let us assume that the probability of
no traffic delay in one period, given no traffic delay in the
preceding period, is 0.9 and that the probability of finding a
traffic delay in one period, given a delay in the preceding period,
is 0.75. Traffic is classified as having either a delay or...

A report by the Traffic Injury Research Foundation stated that
alcohol was a factor in 37 % of accidents causing the fatally
injury of automobile drivers. In a random sample of 12 automobile
accidents resulting in the death of the driver:
a) What is the probability that alcohol was not a factor in any
of the accidents?
b) What is the probability that alcohol was a factor in more
than 2 but less than 7 of the accidents?
c) What...
What is the probability a driver will be taken the hospital this year (as a result of an accident)?
In any given year, an insurance company believes the
following:
-0.6 of drivers are safe.
-0.25 of safe drivers wear seatbelts
-0.10 of unsafe drivers wear seatbelts
-0.10 of safe drivers experience an accident in a year
-0.20 of unsafe drivers experience an accident in a year
-Given a driver experiences an accident, the driver has
probability 0.01 they will be taken to the hospital if they were
wearing a seatbelt
-Given a driver experiences an accident, the driver has...
