Suppose the time between the arrivals of successive cars at a toll booth is measured by a
Question:
Suppose the time between the arrivals of successive cars at a toll booth is measured by a random variable X that is exponentially distributed with the density function
where x measures time (in minutes). Find the probability that a randomly selected pair of successive cars will arrive at the tool booth at least 6 minutes apart.
