Traffic spacing is the time between vehicles (measured in seconds) passing a fixed point. If vehicles travel the road "at random", which would mean "without clumping" then the time between vehicles passing should follow an exponential distribution. On a particular stretch of road, if you pick a spot at random to observe vehicles, the mean time until the next vehicle arrives is 10.0 seconds. Answer the following question assuming that an exponential model with a mean of 10.0 seconds is appropriate.
Find the probability that it is more than 10.0 seconds until the next vehicle arrives and the median between vehicle passes.
