A hotel claims that 90% of its customers are very satisfied with its service. Complete parts a through d below based on a random sample of seven customers.a. What is the probability that exactly six customers are very satisfied?(Round to four decimal places as needed.)b. What is the probability that more than six customers are very satisfied?(Round to four decimal places as needed.)c. What is the probability that less than five customers are very satisfied?(Round to four decimal places as needed.)d. Suppose that of seven customers selected, two responded that they are very satisfied. What conclusions can be drawn about the sample?The probability that 2 out of 7 customers are very satisfied is, assuming that 90% of customers are very satisfied. Therefore, it isresponding that they are very satisfied.(Round to four decimal places as needed.)MacBook Air1that randomly selecting 7 customers would result in 2Time Remaining: 01:56:30Next
