Question 328069
Please help me solve this problem.
The table below describes the smoking habits of a group of asthma sufferers.
	Nonsmokers    Light Smoker  Heavy Smoker   Total
Men	311	82	74	467
Women	329	68	60	457
Total	640	150	134	924
If a woman is randomly selected, find the probability that she is a nonsmoker.
------------
P(nonsmocker|woman) = P(nonsmoke AND woman)/P(woman) = 329/457 = 0.720
