    If a weatherman says the chance of rain is 30%, and it rains, his forecast is not necessarily incorrect. You need repeated trials to confirm accuracy.

    If 10/10 times he predicts a 30% chance of rain it rains, then yeah, he's a bad forecaster.

    If 3/10 times he predicts 30% chance of rain it rains, then he's pretty accurate

      Then if we're talking about an event that will only happen in these circumstances one time, what exactly is the value of these types of predictions? They could have given Trump a 1% chance of winning and still said "well that's not impossible". That's not incorrect, but it sure sounds a lot like ass-covering and it makes you wonder why we even listen to this

        It's valuable because it's interesting. Might help you plan for future events. I might take an umbrella if there is a 30% chance of rain but not if there is a 1% chance

        Keep in mind, it's not just a prediction of the overall result, they are also forecasting each state, D.C., and the popular vote, so it's more like an ensemble of 52 predictions, so you can also judge the accuracy of each of those forecasts as well.
