In Exercise 2.12 we considered a situation where cars entering an intersection each could turn right, turn left, or go straight. An experiment consists of observing two vehicles moving through the intersection.a. How many sample points are there in the sample space? List them.b. Assuming that all sample points are equally likely, what is the probability that at least one car turns left?c. Again assuming equally likely sample points, what is the probability that at most one vehicle turns?

Proposed improvements to Barracks-Emmet intersection include right-turn lanes, expanded bike/pedestrian crossings
