Problem 6E
Starting at a fixed time, each car entering an intersection is observed to see whether it turns left (L), right (R), or goes straight ahead (A). The experiment terminates as soon as a car is observed to turn left. Let X= the number of cars observed. What are possible X values? List five outcomes and their associated X values.
Step-by-Step Solution:
Answer: Step 1 of 1 Here, X is the number of cars observed at an intersection until a car turns Left (L). (Cars can turn right (R), left (L) or go straight (A)). X = 1 Outcome = (L) X = 2 Outcome = (AL, RL) X = 3 Outcome = (AAL, ARL, RAL, RRL) X = 4 Outcome = (AAAL, AARL, ARAL, ARRL, RAAL, RARL, RRAL, RRRL) And so on Thus, X can take on the values 1, 2, 3, 4, ...
