I asked a guy for an answer I needed.
“Are you going to be there?”
“I don’t know, I’m 50/50. But probably.”
Well, isn’t “probably” more than 50-50?
Or maybe at best 51-49?
The other side would be “probably not,” which is trouble because it sounds so less optimistic to the point that you shouldn’t even offer a percentage.
He ended up coming, as I expected — no thanks to percentages.
