Find probability pregnancy lasted 308 days or longer Round to three place


Extracted text: The lengths of pregnancies are normally distributed with a mean of 268 days and a standard deviation of 15 days. One classical use of the normal distribution is inspired by a letter to "Dear Abby" in which a wife claimed to have given birth 308 days after a brief visit from her husband, who was serving in the Navy. Given this information, find the probability of a pregnancy lasting 308 days or longer. (Round to three decimal places)
