What is the probability that a randomly selected person will have a birthday in September? Assume that this person was not born in a leap year. Express your answer as a simplified fraction or a decimal rounded to four decimal places.

Assuming that births are evenly distributed throughout the year:

30 days in September

365 days in a year 

30/365 = 6/73
