An intersection of road with a four-way stop sign has no cars at the intersection 51% of the time, one car at the intersection 6% of the time, two cars at the intersection 21% of
the time, three cars at the intersection 8% of the time, and 4 cars at the intersection during the remaining possible time. Calculate the expected value of the number of cars at this intersection at a randomly selected time. Use two decimal place accuracy.
