Starting at a particular time, each car entering an intersection is observed to see whether it turns left (L) or right (R) or goes straight ahead (S). The experiment terminates as soon as a car is observed to go straight. Let y denote the number of cars observed. What are possible y values? List five different outcomes and their associated y values.
Let x denote the distance from the lower left-hand corner A of the square to the selected point. What are possible values of x? Is x a discrete or a continuous variable?
