Assume that the percentages in the graph are representative of adult Americans. (a) What is the probability that a randomly selected adult American drinks coffee? (b) The display associates 13% with the category "one cup of coffee a week." For the chance experiment that consists of selecting an adult American at random, is 0.13 the probability that the selected individual drinks one cup of coffee a week, or is it the conditional probability that the selected individual drinks one cup of coffee a week given that he or she drinks coffee? Explain. O This is the probability that the selected individual drinks one cup of coffee a week, because that probability is less than 72%, which is the percent of Americans that drink coffee. O This is the conditional probability that the selected individual drinks one cup of coffee a week given that the individual drinks coffee, as the percentages in the display add up to 100. But we know that only 72% of Americans drink coffee, so the percentages must be proportions of coffee drinkers. our ce: USA TODAY, January 8, 2010.

(a) What is the probability that a randomly selected adult American drinks coffee?
(b) The display associates 13% with the category "one cup of coffee a week." For the chance experiment that consists of selecting an adult American at random, is 0.13 the probability
that the selected individual drinks one cup of coffee a week, or is it the conditional probability that the selected individual drinks one cup of coffee a week given that he or she
drinks coffee? Explain.
O This is the probability that the selected individual drinks one cup of coffee a week, because that probability is less than 72%, which is the percent of Americans that drink
coffee.
O This is the conditional probability that the selected individual drinks one cup of coffee a week given that the individual drinks coffee, as the percentages in the display add up
