When a man observed a sobriety checkpoint conducted by a police department, he saw 695 drivers were screened and 5 were arrested for driving while intoxicated. Based on those results, we can estimate that Upper P (Upper W )equals0.00719, where W denotes the event of screening a driver and getting someone who is intoxicated. What does Upper P (Upper W overbar )denote, and what is its value?

Step-by-step explanation:

W denotes the event of screening a driver and getting someone who is intoxicated.

Out of 695 drivers, the man observed that 5 were arrested for driving while intoxicated.

Therefore:

The probability of the complement of event W, denotes the probability of screening a driver and getting someone who is NOT intoxicated.

From probability theory, we know that the sum of the probability of an event and its complement is 1.
