The probability is very close to 0.25
A year is a leap year
if the number is divisible by 4 - except
if the number is divisible by 100 it is not a leap year - except
if the number is divisible by 400 it is a leap year.
So, in a 400-year period there are 97 leap years. The probability or relative frequency of leap years is, therefore, 97/400 = 0.2425
