Question

Verify your answers to part (b) by adding the probabilities of the elementary outcomes in each of A and A B. Consider the two events. A = [Obese] B = [ Male ] for persons in the age group 20-39 years old. A survey taken in early 2009-2010 by the National Center for Health Statistics, suggests the probabilities P(A) =.36 P(B) =.50 P(AB) =.18 for a randomly selected person. Enter these probabilities in the following table. Determine the probabilities of AB, AB, and AB and fill in the table. Refer to Express the following events in set notation and find their probabilities. B occurs and A does not occur. Neither A nor B occurs.
