So... all we know is that there is a son that was born on a Tuesday. The other child was born either before or after him. Maybe even on the same day. The possibilites are: He has an older brother. He has a younger brother. He has an older sister. He has a younger sister. The specific weekday doesn't matter at all. The answer is 2/4.

The difficult we do today; the impossible takes a little longer.
