John and mary were born in different years during the XX century.

What's the probability that the sum of their year of birth is 3875?

This is just a simple combination question,
John and mary were born between 1900-1999,
We also know they are born in different years
If john was born between 1900-1975 then there would be a year Mary could be born to satisfy the condition
Which means there is exactly 75 ways this could work
Note, since 3875 is an odd number none of the possibilies can involve both Mary and John being born in the same year
There is 99*98(Since different years) ways for them to be born
So I think the answer is 75/(99*98)

Wrong, it's 37/4950
