What is the probability that a random person has a birthday in July?

A simple answer is 1/12 = 0.0833... since there are 12 months in a year, of which 1 has been selected.
A slightly better estimate, allowing for the the fact that July has 31 days is 31/365 = 0.0849. Adjusting for leap years does not affect the probability at 4 decimal places.
These answers assume that births are uniformly distributed over the year. In fact they are not but comprehensive information on births by month is not readily available.
