Fraction of families with more than 3 pets =
Step-by-step explanation:
The proof can be done by contradiction. Suppose both a, and b weren't even. So that a, and b are both odd. This means they both look like
(for some integers k and l)
So, let's compute what would be in this case:
which notice wouldn't be divisible by 4. This shows then that since is divisible by 4, at least one of the integers a and b is even.
