Calculating dealers bust chance

Hello there, i was wondering if someone could post the calculations for calculating the dealer's bust chance when the dealer is showing a 6 in a six deck game. I have found several tables on the internet but none include the math behind them.

There is no easy formula. You pretty much have to loop through all the way the cards can come out via computer. If you can live with an infinite deck you can fairly easily solve the problem in a spreadsheet, but starting with the probability of busing with a 16-21, and recursively moving backwards until you get to 6.

Thanks for your reaction, this is what i feared but i was kinda hoping that you might have done these calculations and had them lying around somewhere to share with the world:P

I do have them just laying around.
