Historically, a wealth management firm has a 20% conversion rate of turning potential customers into actual customers. During a particular week, the firm targeted 15 potential customers in the hope of converting them into actual customers. What is the probability (rounded to four digits after the decimal) that seven out of the 15 potential customers targeted become “actual customers” for the firm?

During a particular week, the firm targeted 15 potential customers in the hope of converting them into actual customers. What is the probability (rounded to four digits after the decimal) that less than 11 out of the 15 potential customers targeted become “actual customers” for the firm?

Flight landings at a regional airport are independent in any ten-minute slot during peak hours. The probability of flight landings at the airport in any ten-minute slot during peak hours remains the same. Based on historical data, five flights are expected to land at this airport in a ten-minute slot during peak hours. You are interested in streamlining and improving the process of flight landings at this airport. We need to find the probability that less than five flights land at this airport in ten-minutes during peak hours. What is the correct Excel formula (among the ones listed below) that will help us find the answer?
