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 (5). The experiment terminates as soon as a car is observed to go straight. Suppose that the random variable y denotes the number of cars observed. (a) What are possible y-values? O all positive real numbers O all whole numbers greater than 1 O all real numbers greater than 1 O all integers Ⓒall positive whole numbers (b) List five different outcomes and their associated y-values. Outcome Value of y RRS LRRRLS RALLS S RRRS
