According to one study among a certain people group, pregnancy lengths are approximately normally distributed with a mean of 267 days and a standard deviation of 7 days. Approximately 12.7% of babies are premature, which means that they are born before 37 weeks in the pregnancy. A random sample of 75 pregnant women from this people group is observed and the length of each pregnancy is tracked. Let X be the number of premature babies born to these mothers.
What is the probability that more than 14 premature babies are born to these mothers?
