The Probability of Being in an Accident Increases as a Driver's

Multiple Choice

The probability of being in an accident increases as a driver's blood-alcohol content (BAC) rises. It has been observed that the probability rises faster and faster as the BAC increases. Let ^P(x) be the probability that a driver will be involved in an accident as a function of x, the driver's BAC. Let L be the BAC at or above which it is illegal to drive. Let ^{b = P(0)} What is the meaning of
P^-1(6b) ?

A) The probability of an accident for someone who has had 6 drinks.
B) 6 times the probability of an accident for someone who hasn't been drinking.
C) The BAC at which the probability of an accident is 6 times that of a person who hasn't been drinking.
D) The BAC at which the probability of an accident is 6 times that of a person whose BAC is at the legal level.
