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?

Reference

A vehicle arriving at an intersection can turn right, turn left, or continue straight ahead. The experiment consists of observing the movement of a single vehicle through the intersection.

a. List the sample space for this experiment.

b. Assuming that all sample points are equally likely, find the probability that the vehicle turns.
