Asked by Daniela

When Dominic commutes to work, the amount of time it takes him to arrive is normally distributed with a mean of 26 minutes and a standard deviation of 3 minutes. Out of the 269 days that Dominic commutes to work per year, how many times would his commute be between 28 and 31 minutes, to the nearest whole number?
