The U.S. Census Bureau's 2012 population estimate was that for individuals 18 or over, 48.2% were men and 51.8% were women. This exercise addresses this age group.

The probability that the driver is a woman and stops to ask for directions is found by multiplying the probability that the driver is a woman (51.8% or 0.518) by the probability that a woman would stop and ask for directions (61% or 0.61). This calculation is 0.518 * 0.61 = 0.316.
