Question 924024: Police plan to enforce speed limits by using radar
traps at four different locations within the city limits.
The radar traps at each of the locations L1, L2, L3,
and L4 will be operated 40%, 30%, 20%, and 30% of the time. If a person who is speeding on her way to
work has probabilities of 0.2, 0.1, 0.5, and 0.2, respectively,
of passing through these locations, what is the
probability that she will receive a speeding ticket?
