He said Trump had a 28% chance of winning, and Trump won. So he was also “right.” Do you see now why what you’re saying is incorrect?

Suppose I said Trump had a 72% chance of winning the same election, which Trump won. Am I also “right”?

If so, how can it be that Trump has a 28% chance of winning and a 72% chance of winning?

If not, why is he right instead of me?
