DRAWING CONCLUSIONS A survey of 2392 adults that are each a different color. A marble is drawn, ages 18 and over asked what type of food they would its color is recorded, and then the marble is placed be most likely to choose at a restaurant. The results back in the bag. This process is repeated until 30 are shown in the figure. What is the probability that an marbles have been drawn. The table shows the results. adult chosen at random prefers Italian food?
