Answer:
I think it's more likely than not that Biden wins. (Perhaps a 60 percent chance.) However, anything can happen, and it's going to be very close.
There's 6 states left that are too close to call. They are: Nevada, Wisconsin, Michigan, Pennsylvania, North Carolina, and Georgia. Biden is at 238 electoral votes, Trump is at 213 electoral votes. You need 270 to win.
Based on what's happening so far, I believe Nevada, Wisconsin, and Michigan will lean for Biden. I believe Georgia and North Carolina will more likely than not lean for Trump. This puts Biden at 270, and Trump at 248. If Pennsylvania goes for Trump, it will be 270-268, with Biden winning.
These are just my personal predictions. Anything can happen, and it's going to be a very tight race. However, I believe Biden has a slightly higher chance of reaching 270 than Trump does.
