When a man observed a sobriety checkpoint conducted by a police department, he saw 672 drivers were screened and 55 were arrested for driving while intoxocated Based on those results, we can estimate that P(w)=0.00744, 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(W) represent?

a. P(W) denotes the probability of driver being intoxicated

b. P(W) denotes the probability of a driver passing through the sobriety checkpoint y

c. P(w) denotes the probability of screening a driver and finding that he or she is not intoxicated

d. P (W) denotes the probability of screening a driver and finding that he or she is intoxicated

## Answers ( )

Answer:c. P(w) denotes the probability of screening a driver and finding that he or she is not intoxicated

Step-by-step explanation:P(W¯¯) denotes the probability that a given person is not intoxicated when screened

because P(W¯¯) is the probability all possible outcomes that are not a part of W

P(W¯¯) = 1 – P(W)

P(W¯¯) = 1 – 0.00744

P(W¯¯) = 0.99256
