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
