There is a 60% chance a computer server will stay operational (i. e. doesn't crash) all day. if a company's website uses 3 servers acting independently, find the probability that the site stays up all day (i. e. find the probability that at least 1 server stays operational all day). leave your answer as a decimal and do not round. hint: first use the complement rule to find the probability a single server crashes in a day. then use the multiplication rule to find the probability that all servers will crash in a day. then, finally, use the complement rule again to find the probability that at least one stays operational all day.
