Question

Men have a reputation for not wanting to ask for directions. A Harris study conducted for Lincoln Mercury indicated that​ 42% of men and​ 61% of women would stop and ask for directions. 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. A randomly chosen driver gets lost on a road trip. Determine the probability that the driver is a woman and stops to ask for directions.

Answer 1

0.316

Explanation:

Defining

p(A): probability that the driver is a woman = 0.518

p(B): probability that a woman stops to ask for directions = 0.61

Then, the probability that the driver is a woman and stops to ask for directions is

p(A)*p(B) = 0.518*0.61 = 0.316
