Some researchers claim there is an association between taking vitamins and gaining weight. They took a random sample of people
living in Boston, Massachusetts, and recorded whether they took vitamins and whether they gained weight. The results are shown in
the following two-way table:
Has Gained Weight Has Not Gained Weight
Does not take vitamins
Takes one vitamin per day
Takes more than one vitamin per day 72
If a person is chosen at random, what is the probability that he or she has gained weight, given that he or she takes more than one
vitamin per day?
0.42
0.45
0.47
