Based on past surveys over several years, a small business believes that 75% of their customers are satisfied with their services. Due to the recent conditions, changes in policy and additional charges, the business decides to select a random sample of 16 recent customers and ask them if they are satisfied with their services. If the number of satisfied customers in the sample is 11 or fewer, the business will conclude that this is an indication of a need for improvement in customer service and they will try to determine ways to provide it. What is the probability that the results of the sample will indicate a need to improve customer service?
