2. You manage personnel for a tax accounting firm. Your firm has a retail location where customers walk in without appointment to have their 1040 tax return prepared. On an average day in March, 20 people walk in per day to have their return prepared. What is the probability that at least 25 people will come today to have their tax returns prepared?
