How many coin flips would you need inorder to notice that the coin you were flipping was not a 50/50 coin, and instead possessed the probabilities shown above? Something like 52%/48%?

You would need about 100 flips just to get the distributions with enough resolution to distinguish 52/48 from 50/50 and then you would probably need atleast an additional 100 flips for you to be reasonably sure you didn’t have a little bad luck as even a fair coin (50/50) is unlikely to give you exactly a 50/50 split in real flips. And depending on how certain you wanted to be more flips further. This event is going to happen once. Not 100, 200, or more times. “Clear advantage for Trump side”, Is a misreading of the implied probabilities. This is fundamentally a coin flip based on the numbers shown it has about the most uncertainty possible for an event which has only two outcomes.
