When things are operating properly, a certain Internet bank can process a maximum of 27 electronic transfers every minute during the busiest periods of the day. If it receives more transfer requests than this, then the bank's computer system will become so overburdened that it will slow to the point that no electronic transfers can be handled. If during the busiest periods of the day requests for electronic transfers arrive at the rate of 180 per 10-minute period on average, what is the probability that the system will be overwhelmed by requests? Assume that the process can be described using a Poisson distribution The probability that the system will be overwhelmed by requests is (Round to four decimal places as needed.)
