I bet the old yeast will be OK. Is it dry or liquid? If liquid, make a starter (which you should probably do anyway). How has it been stored? If it was dry yeast, and it was refrigerated, I'm sure it'll be fine. As long as it hasn't been exposed to really high temps for an extended period, I would think it would work. But if it's just dry yeast, and you think it's suspect, I'd just buy another pack (what does it cost, anyway, 2-3 bucks?).

It's probably fine. That being said, you might want to make yourself a starter to be certain.

It should be fine as long as you make a good starter with it.

I got washed yeast in fridge that is nearly a year old and it still works fine. Yeast are amazing!
