When a man observed a sobriety checkpoint conducted by a police department, he saw 654 drivers were screened and 8 were arrested for driving while intoxicated. Based on those results, we can estimate that P(w) 0.01223, where W denotes the event of screening a driver and getting someone who is intoxicated. What does P (W) denote, and what is its value? What does P() represent? OA. P(W) denotes the probability of screening a driver and finding that he or she...
