Well, that one is a little bit more simple.

Barrel A, Barrel B, and Barrel C
Fruit - Apples -- Oranges

If he pulls Apples out of Barrel A, you apply Apples to Barrel A,
Oranges to Barrel B and Fruit to Barrel C, just a matter of making sure
the same label doesn't end up on the same spot.

In the case of the game show problem however, you start out with 3
choices to resolve the situation:

2 Losses
1 Win

No matter what you choose, the situation is simplified to two choices:

1 Loss
1 Win

The other properties of the choice don't change, as there will always be
1 win and 1 loss. Nothing says either or will be more probable than the
other, so you should end up with a 50/50 chance.
