P(BAC = 0 | Crash with fatality) = .616P(BAC is between .01 and .09 | Crash with fatality) = .300
P(BAC is greater than .09 | Crash with fatality) = .084
Over a certain stretch of highway during a 1-year period, suppose the probability of being involved in a crash that results in at least one fatality is .01. It has been estimated that 12% of the drivers on this highway drive while their BAC is greater than .09. Determine the probability of a crash with at least one fatality if a driver drives while legally intoxicated (BAC greater than .09).
