M4 Use of acceleration lane. A study of vehicle flow characteristics on acceleration lanes (i.e,, merging ramps) at a major freeway in Israel found that one out of every six vehicles uses less than one-third of the acceleration lane before merging into traffic (Journal of Transportation Engineering, Nov. 1985). Suppose we monitor the location of the merge for the next five vehicles that enter the acceleration lane. a. What is the probability that none of the vehicles will use less than one-third of the acceleration lane? bh. What is the probability that exactly two of the vehicles will use less than one-third of the acceleration lane
