Question 325894
The table below describes the smoking habits of a group of asthma sufferers.
      nonsmoker  light smoker   heavy smoker   total
men     381        88               77          546
women   346        78               89          513
total   727        166              166         1059



If one of the 1059 subjects is randomly selected, find the probability that the person chosen is a nonsmoker given that it is a woman. Round to the nearest thousandth.
-----
The denominator is the # of women = 513
The numerator is the # of nonsmokers in that line = 346
---
Ans = 346/513 = 0.6745
