Question 1168794: Scientific research on popular beverages consisted of 60 studies that were fully sponsored by the food industry, and 40 studies that were conducted with no corporate ties. Of those that were fully sponsored by the food industry, 15 % of the participants found the products unfavorable, 23 % were neutral, and 62 % found the products favorable. Of those that had no industry funding, 38 % found the products unfavorable, 15 % were neutral, and 47 % found the products favorable. If a randomly selected participant found the product unfavorable, what is the probability that the study had no industry funding?
