The following data represent the number of drivers involved in a fatal crash in 2016 in various light and weather conditions. Complete parts (a) through (e) below.
Click the icon to view the table of fatal crashes in various light and weather conditions.
(b) Determine the probability that a randomly selected fatal crash in 2016 occurred in daylight.
P(Daylight) = 479 (Round to three decimal places as needed.)
(c) Determine the probability that a randomly selected fatal crash in 2016 occurred in normal weather and in daylight.
P(Normal and Daylight) = 420 (Round to three decimal places as needed.)
(d) Determine the probability that a randomly selected fatal crash in 2016 occurred in normal weather or in daylight
P(Normal or Daylight) = 917 (Round to three decimal places as needed.)
(e) Would it be unusual for a fatal crash in 2016 to occur while it is dark outside (without lighting) and raining? (For the purposes of this exercise, consider a probability less than 0.05 to be low.)
It would be unusual for a fatal crash in 2016 to occur while it is dark outside (without lighting) and raining because the probability P(Raining and Dark without lighting) = .020 is low.
(Round to three decimal places as needed.)
Why might this result be considered misleading? Select all that apply.
A. Common sense indicates that a dark (without lighting) road in the rain is dangerous, so it seems that the probability of a fatality should be high.
B. A better question would be "Among the drivers on the road when it is dark and raining, what proportion result in a fatality?"
C. There are likely to be fewer drivers on the road at night, especially when it is raining.
D. The result is not misleading.
