Question: A study collects data that shows the distribution of BMI in children living in U.S. and European urban neighborhoods. In each of the following categories, the data are in millions. In U.S. urban neighborhoods, 125 M are found to be in the normal weight range, 50 M overweight, and 40 M obese. In European neighborhoods, 101 M are found to be in the normal weight range, 42 M overweight, and 21 M obese.
If a child is selected at random, what is the probability that the child is in the overweight category?
