In a certain municipality, 70% of all residents are at risk of heart disease. If researchers randomly selected 16 of these residents and let the random variable X be the number of residents who are at risk of heart disease, what is the probability that at least 10 but not more than 13 of the residents would be at risk for heart disease? Round off to 4 decimal places.
