Accuracy in taking orders at a drive-through window is an important feature for fast food chains. Accuracy is the measured as the percentage of orders consisting of a main item, side item, and drink that are filled correctly. In a recent month, suppose that the percentage of correct orders of this type filled at Burger King was approximately 88%. If a sample of three orders is taken.     b. Suppose that you and two friends go to the drive-through window at Burger King, and each of you place an order of the type just mentioned. What are the probabilities that all three, that none of the drive, and that at least two of the three orders will be filled accurately?
