A DUI checkpoint was set up downtown on a Saturday night (pre-Covid), and 150 people took a breathalyzer test. The table above gives the number of men and women who registered in four different ranges of blood-alcohol concentration (BAC).
If one person is randomly selected from this DUI checkpoint group, what is the probability the driver was in the lowest BAC range (0.00 - 0.04%) and therefore "should" be ok to drive?
Give your answer as a decimal number rounded to nearest thousandths place (like 0.123).
