Estimate probability of observer counting exactly 4-vechile

Reference no: EM13303112

an observer has determined that the time headways between successive vechile on a section of the highway are exponentially distributed and that 65% of the headways btw vehicles are 9 seconds or greater. if the observer decides to count traffic in 30 second time interval, estimate the probability of the observer counting exactly four vehicles in an interval.
