How to answer this question

Question 1 Accuracy in taking orders at a drive-through window is important for fast-food chains. Each month, OSR Magazine, www.qsrmagazine.com, publishes the results of its surveys. Accuracy is measured as the percentage of orders that are filled correctly. In a recent month, the percentage of orders filled correctly at Mcdonald's was approximately 91%. Suppose that you and ten friends go to the drive through window at Mcdonald's and independently place orders, what is the probability that at least 7 orders will be filled correctly? what is the probability that between 3 and 9 orders will be filled correctly? what is the probability that not more than 5 orders will NOT be filled correctly
