If you actually took the time to read the OP, you would see that you have extra information that says that this is absolute rubbish in this case, I wouldn't need to look it up without that.
Probabilities are skewed by the fact that W has 6 hearts to E's one, and that YOU CANNOT EVER GET BACK TO DUMMY as was clearly stated.
So if I got it right this time east can trump a h if the finesse fails.
If so playing the ace is the best option to loose only 1 trick.
