Asurvey of eating habits showed that approx 4% of people in a certain city are vegans. a restaurant in the city expects 400 people on opening night, and the chef is deciding on the menu. treat the patrons as simple random sample from the city and the surrounding area, which has a population of about 600,000. if 18 vegan meals are avail, what is the approx. probabbility that there will not be enough vegan meals-- that is, the probability that 19 or more vegans will come to the restaurant? assume the vegans are independent and there are no families of vegans.
