In: Statistics and Probability
The truck traffic on a highway can be describe as a Poisson
process with a mean arrival rate of 1.5 trucks per minute. The
weight of each truck is random and the probability that a truck is
overloaded is 5%.
a. What is the probability that there will be at least
two trucks passing a weigh stat ion this highway in a 10-minute
period? Define the random variable.
b. What is the probability that at most one of the next
10 trucks stopping at the weigh station will be overloaded? Define
the random variable.
c. Suppose the weigh station will close for 30 minutes
for lunch. What is the probability of overloaded trucks passing the
weigh station during the lunch break? Define the random
variable.
