You roll two fair 6-sided dice.

One of them is a 6.

What are the odds that the other is also a six?

Okay, there's four possibilities:
1) *The one that's a six is a six, and the other one is a six
2) *The one that's a six is a six, and the other one is not a six
3) *The one that's a six is not a six, and the other one is a six
4) *The one that's a six is not a six, and the other one is not a six.

Clearly, we can eliminate 3) and 4). That leaves us with a 1 in 6 probability that the die other than the die that's a six is also a six.

(alternate, smart-ass answer: the odds are 0, because 'one of them' means 'exactly one of them'.)
