Independent Events Based on a KRC Research survey, when 1020 adults were asked about hand hygiene, 44% said that they wash their hands after using public transportation. Consider the probability that among 30 different adults randomly selected from the 1020 who were surveyed, there are at least 10 who wash their hands after using public transportation. Given that these subjects were selected without replacement, are the 30 selections independent? Can they be treated as being independent? Can the probability be found using the binomial probability formula?
